President’s Column 

by James Mullarkey 

Vote 

Yes, this month is the month 

that all RMAG Members, and RMAG 

Honorary Members will receive their 

ballots to cast your vote for your 

Association’s leadership for the next 

year to two years. PLEASE VOTE. The 

Secretary is the one year post, with 

the President-Elect, Treasurer-Elect, 

and the two Year Counselor, spending 

two years on the RMAG Board of 

Directors. The First and Second Vice 

Presidents serve one year on the 

Board of Directors and then chair 

the Publications Committee and the 

Continuing Education Committees, 

respectively, the following year. 

The voting will be open through 

Tuesday, December 1st at 4 PM 

(MST) with the results reported 

at the Friday Luncheon-Annual 

Meeting on December 4th. But don’t 

procrastinate, gather the information 

you need and make an informed 

choice. The diffi culty will be choosing 

from this slate of great candidates for 

next year’s RMAG Board of Directors. 

Big thanks are due to this year’s six 

person Nominating Committee and 

the twelve Candidates. The Ballot 

Committee has decided to place 

a ballot box in the RMAG offi ce so 

members can drop their ballots off 

if they would prefer, rather than 

mailing them to the offi ce. This year 

the Board chose RMAG Members 

to comprise the Nominations and 

Ballot Committees, as called for in the 

RMAG Bylaws. The U. S. Postal Service 

should deliver your ballot within days 

of the arrival of this issue of the 

Outcrop. The chair of the Nominations 

Committee is Steven Goolsby and 

the chair of the Ballot Committee is 

Michele Bishop, please contact any of 

the Board, or either of them with your 

thoughts or comments. 

The RMAG office staff was 

reduced to two full time permanent 

employees, Sandi and Josh, when 

Caitlyn, resigned on 8-19-2009. So 

if you can stop by the offi ce and lend 

a hand it would be appreciated I am 

certain. Please call or e-mail the 

offi ce ahead of time if you can lend 

a hand. 

With winter approaching, this 

month’s initial energy saving fact 

falls back to an old standby, add 

insulation. An estimated 80% of 

older homes are under-insulated. 

Properly insulating and sealing your 

home can cut your heating and 

cooling bills by 10% (reference: 

ConsumerReports, October 2008, p. 

23, consumerreports.org). The target 

R value for attic insulation in Parker, 

Colorado, about 15 miles from where 

I live, but in the same general ZIP 

code, is 38. This fact is from the www. 

energysavers.gov website, search 

on “zip-code insulation program”; I 

used the R-Value Recommendations 

Calculator, which uses 2002 cost 

data. If your attic has less than 11 

inches of fiberglass or rock wool 

or 8 inches of cellulose, you would 

probably benefit by adding more 

according to ConsumerReports 

(reference: ConsumerReports, 

October 2009, p. 22) Professional 

energy auditors use a blower door 

or infared photography to pinpoint

Lead Story 

Nebraska – The New Uranium Frontier 

By Steven S. Sibray and Dr. Marvin Carlson 

INTRODUCTION 

When people think of resources found in Nebraska, they might think of corn or cattle. Rarely do they think in 

terms of nuclear energy and new technology. Yet Nebraska has been a signifi cant producer of uranium since 1991 

and is arguably one of the most underexplored uranium provinces. The Crow Butte mine near Crawford, Nebraska has 

produced a little over 13 million pounds of uranium utilizing the innovative in situ recovery [ISR] technology. This low 

cost and high tech method of uranium mining has allowed Crow Butte Resources to develop this world class deposit 

during a period of record low uranium prices (around $10/lb). In recent years, uranium spot prices have been volatile, 

increasing to over $130/lb and then falling back down to around $48.00/lb. Despite the dramatic price increase, 

there is only one company actively exploring for uranium in the state. 

The uranium mineralization at 

the Crow Butte mine occurs as a 

classic “roll front” deposit (see Fig. 

1). Roll front deposits form when 

oxygen rich groundwater carrying 

high concentration of hexivalent 

uranium (U+6) encounters low 

oxygen groundwater and precipitates 

tetravalent uranium (U+4) minerals 

such as coffi nite and /or uraninite. 

Iron minerals in the aquifer typically 

change from pyrite on the down 

gradient side of the oxidation front to 

hematite on the oxidized side of the 

interface. The change in iron mineral 

is very visible in drill cuttings and 

can be very useful as an exploration 

guide. 

ISR technology utilizes the fact 

that uranium is very soluble in the 

presence of oxygen rich water. Oxygen 

enriched water is injected into the 

uranium bearing sand/sandstone 

to oxidize and dissolve the uranium 

minerals. The uranium rich solution is 

then pumped out and piped to an ion 

exchange plant where it is processed 

and the water is then recycled back 

to the well fi eld. 

The uranium roll front deposits 

at the Crow Butte mine occur in the 

basal sands of the Chamberlain Pass 

Formation (CPF) which is the oldest 

part of the White River Group (WRG) 

of Eocene age (see Fig. 2). The CPF 

consists of a basal white to greenish 

white sand or sandstone composed 

of coarse grains of quartz, quartzite, 

and chert. Extensive chemical 

weathering including the removal 

of iron and kaolinization give the 

sandstone a “bleached” appearance. 

The sandstone thickness varies from 

0 to 350 feet and unconformably 

overlies the Cretaceous Pierre Shale 

or the Yellow Mounds Paleosol. 

The uppermost part of the CPF 

consists of the bright red Interior 

Paleosol. The Chadron Formation 

(CF) unconformably overlies these 

paleosols and consists of bluish 

green mudstones; thin, interbedded, 

lacustrine limestone beds; and

all or a of leadership days (ALD) in Tulsa, OK representing the 

RMAG as your president. The ALD is an annual AAPG 

sponsored event. There were about 120 attendees plus 

more than 30 AAPG staff involved in this 3 day event. 

The central topic was communication, especially at 

the committee level and with the AAPG headquarters. 

There were nine focus/breakout sessions held and the 

PowerPoint summaries of each will be made available on 

the AAPG website (search on “L” or 

“leadership” and you should fi nd the 

summaries). The attendees included 

about 20 Young Professionals 

representing 15 student chapters 

in 9 countries, including the U.S.A. 

These younger folks gave the get 

together an infusion of energy 

and stimulated discussion of what 

younger geologists can contribute 

to professional societies and what 

they would like to see from the 

older members, and also from 

professional societies in general. I 

found it to be an exciting, informative 

and worthwhile event. 

I have a couple of jokes to close 

out this month’s column. What did 

the mathematician say when he 

lost his parrot?…Where’s my Pollygon? 

And, Johnnie’s mom asks 

him “Johnnie, there were two pieces 

of chocolate cake in the kitchen 

and now there’s only one. Can 

you explain that? ” Johnnie answers, 

“I guess I didn’t see the other 

piece!”

Lead Story 


localized channel 

sandstone deposits. 

In areas where the CF 

paleochannels have 

completely removed 

the CPF, the CF sands 

rest directly on top of 

the Cretaceous Pierre 

Shale. The CF sands 

are arkosic and contain 

more weatherable 

minerals than the CPF. 

Differentiation of the two 

sandstones is likely a 

critical factor in exploring 

for uranium. 

The tuffaceous 

WRG rocks have long 

been considered the 

source of uranium in 

the Tertiary basins of 

Wyoming. Although the 

overlaying Chadron 

Formation bentonitic 

mudstones might be 

considered a source 

of uranium, evidence 

from paleohydrogeology 

(tufas and lacustrine 

limestone) suggests that 

groundwater table was 

high and groundwater 

discharge was largely 

local. In contrast, 

groundwater during the 

development of the Interior Paleosol Equivalent was 

largely oxidizing and groundwater fl ow was downward into 

the underlying aquifers 

(CPF and older units). 

The initial uranium 

mineralization at Crow 

Butte probably occurred 

during the development 

of the Interior Paleosol 

Equivalent at the 

CPF-CF unconformity. 

In Nebraska and 

Wyoming, the parent 

material for the Interior 

Paleosol Equivalent 

was the tuffaceous 

WRG. In South Dakota, 

the parent material 

appears to be the Yellow 

Mounds Paleosol which 

would be depleted in 

uranium in comparison 

to the volcanic glass 

found in the WRG 

sediments. 

Exploration efforts 

should consider these 

hydrostratigraphic 

relationships and be 

directed to the CPF 

sands underlying 

the Interior Paleosol 

Equivalent in Nebraska 

and Wyoming rather 

than the CF sands. The 

distribution of the CPF 

sands in Nebraska is 

shown in Figure 3. The highest probability of fi nding 


Figure 1. Vertical cross section of uranium roll front deposit. Uranium precipitates at 

the interface between oxygen rich groundwater and oxygen poor groundwater. Iron 

minerals change from hematite to pyrite at the oxidation front and this is often used as 

an exploration tool. 

Figure 2. Stratigraphic relationships of the lower part of the lower part of the White River 

Group. The older Chamberlain Pass Formation is separated from the Chadron Formation 

by an unconformity and a sequence bounding paleosol [Interior Paleosol Equivalent].

Lead Story 


Figure 3. Distribution of sands in the Chamberlain Pass Formation. Highest probability for 

uranium roll front deposits is along the margins of the main paleovalley entering Nebraska from 

Wyoming in northern Sioux Co. Map from Swinehart et al. 1985 

uranium is along the margins of the main paleochannel which 

trends northwest to southeast from northern Sioux county 

to Cheyenne and Duel counties in the southern Nebraska 

Panhandle. The depth to the base of the CPF in most of this 

area is less than 1500 ft. When uranium prices increase due 

to projected future demand and supply constraints, Nebraska 

may become a signifi cant uranium exploration frontier.

addition to his wife and two children, the family has grown by three: a daughterby-marriage 

and two young grandchildren. Four year old Bella and 23 month old 

Colt live near San Antonio, so spending time with them also involves travel. Ed 

also enjoys reading and outdoor activities such as hiking, biking, camping and 

snowshoeing. In recent years, he’s become increasingly interested in genealogy, 

a passion shared by his wife, and the two of them are devoting considerable time 

to the pursuit of their family histories. 


Over the years, Ed has included community activities in his busy schedule as time 

permitted. He has coached midget football, served on the board of directors 

of the Denver YMCA, held several offices (including co-president) in the Clear 

Creek Booster Club, and donated nearly eight gallons of blood to the Children’s 

Hospital of Denver.

RMAG Foundation – Award for Excellence in Teaching 

Earth Sciences 2009 

This is the ninth year that the Rocky Mountain 

Association of Geologists Foundation has honored a 

teacher that actively promotes excellence in teaching 

of earth science with its “Teacher of the Year Award.” 

The recipient receives a plaque and a cash award, 

provided by the RMAG Foundation, and it is the generous 

donations and supporters of the Foundation that make 

this all possible. A subcommittee of the K-12 Education 

and Public Outreach Committee solicits and judges 

applications submitted by teachers from throughout the 

Front Range area. 

The 2009 recipient of our Excellence in Teaching 

Award is Ms. Anne Burnette. Anne holds a B.S. degree 

in geology and B.A. degree in Environmental Studies 

from Oberlin College, and earned the M.S. degree in 

Journalism with emphasis in science communication 

and writing from the University of Colorado, Boulder. She 

has been a teacher for 8 years and for the last four years 

has been a high school science teacher at the Rocky 

Mountain School for Expeditionary Learning in Denver. 

Her colleagues attest that she brings impressive 

content to her classes at a very challenging level, 

and engages her students in the scientifi c process of 

discovery with authentic and appealing activities. In the 

school’s science curriculum, earth science is taught 

Neo-Geo Adventure, 

Round One 

By Cat Campbell 

“Should we not get too close to 

that?” questioned a weary Neo-Geo 

eyeing the uranium roll front looming 

in the outcrop above. The question 

was rapidly dismissed as we all stood 

in awe of the rock containing oil stains, 

the infamous roll front, a nice yellow 

dusting of sulfur, and many other sedimentary features. 

This was but one of the numerous outcrops visited in the 

front range between Morrison and Golden by a group of 

10 Neo-Geos led by Steve Sonnenberg from the School 

of Mines on August 8th. 

The tour was only a glimpse into the incredible rocks

in the fall trimester to junior 

and senior level students. 

Her curriculum begins with an 

introduction to the scientifi c 

method and how it is used 

in earth science. This is followed by introductions on 

minerals and rocks, structural geology, and the principles 

of plate tectonics and its relationship to the formation 

and distribution of mineral deposits. She also focuses on 

the biogeochemical cycles in nature and the importance 

of the extractive industries on humankind, including the 

concepts of renewable and non-renewable resources. 

She actively promotes fi eld excursions and has taken her 

students to the fi eld with trips to the Edgar Mine (the CSM 

experimental mine in Idaho Springs) and to the Climax 

Mine in Leadville. 

Anne Burnett is an exceptional teacher and an 

outstanding example of those dedicated educators who 

make a signifi cant and positive impact on our children. 

We owe our gratitude to people like Anne for developing 

young minds and planting the seed of interest and 

appreciation of geology. She represents the best of those 

who teach earth science and is a very deserving educator 

worthy to be presented the RMAG’s 2009 Teacher of the 

Year Award. 

» 

that surround our everyday 

lives just a few miles from 

Denver. Peter Bucknam, the 

trip organizer summarizes, 

“We ran the trip to give 

younger geologists an 

introduction to the geology 

of the Denver area, starting 

from the base of our strat 

column and working up. 

We’re lucky to have such 

a great exposure so close 

to town.” 

Several future trips are planned, including a 

continuation of this front range sequence to look at the 

Lyons and Fountain Formations north of our last trip. 

These trips are free for interested geologists, keep your 

eyes on the Outcrop for upcoming dates!

Anatomy and Development of a Low-accommodation Clastic Wedge: Cordilleran 

Foreland Basin, Utah and Colorado, USA 

Jennifer L. Aschoff, Assistant Professor, Stratigraphy, Department of Geology and Geological Engineering, 

Colorado School of Mines, Golden, Colorado, jaschoff@mines.edu, October 2, 2009 

Low aspect-ratio 

wedges typically consist 

of numerous incomplete, 

amalgamated and 

offl apping sequences 

with longer shoreline 

tongues that stack in a 

fl at to falling pattern; 

these characteristics 

are the hallmarks of 

a low-accommodation 

setting. 

Distinguishing sequence architecture within a regional stratigraphic framework 

provides insight into long-, and short-term processes of foreland basin development. 

Two main types of clastic wedges are identifi ed in Cretaceous Cordilleran Foreland 

basin fi ll based on their sequence architecture: (1) thick, vertically stacked, high 

aspect ratio wedges and (2) thinner, more extensive, low aspect ratio wedges. Lowaspect-ratio 

wedges are relatively rare in the Cordilleran foreland basin, and record 

a complex interplay of tectonic styles, climatic conditions and eustatic processes. 

Low aspect-ratio wedges typically consist of numerous incomplete, amalgamated 

and offl apping sequences with longer shoreline tongues that stack in a fl at to falling 

pattern; these characteristics are the hallmarks of a low-accommodation setting. This 

clastic wedge consists of twenty-fi ve facies assemblages and six key parasequence 

types that stack into 3rd-, 4th- and 5th-order depositional sequences and sequence 

sets. High-order sequences stack in a striking offl apping pattern and contain a 

high proportion of tidally infl uenced facies with numerous incisions. Sequencestratigraphic 

and biostratigraphic correlation, coupled with thinning trends indicate 

that the wedge developed coeval with Sevier- and Laramide-style deformation. The 

unique, low aspect ratio clastic wedge records an overlap in deformation style that 

may have interfered with the thrust-belt-controlled fl exural wavelength of the foreland 

basin and changed accommodation patterns. Such clastic wedges are observed in 

other parts of the Cordilleran Foreland basin and may have formed under similar 

conditions. Classifi cation of clastic wedges and careful description of the internal 

architecture of them can provide a unique predictive tool for exploration. This study 

describes one of these unique, low-aspect-ratio (i.e., low accommodation) clastic 

wedges and proposes their utility as an indicator of change in tectonic style and as 

a predictive tool for internal facies types and connectivity.

structurally high 

central core, with 

two surrounding 

structurally high 

areas; an inner and an 

outer rim. The total 

deformed area is 

about 65 square km; 

the central core area 

is 2.6 square km. . 

The Red Wing Creek Field in the Williston Basin of western North Dakota is one of 

a handful of oil and gas fi elds in the world that is known to produce from a structure 

that formed associated with a meteorite impact. Discovered in 1972, this fi eld has 

produced 17 millions barrels of oil and 25 BCF of gas from 26 wells, of which 22 are 

still producing. Ultimate recovery is estimated to be at least 60 million barrels of oil. 

The impact crater consists of a structurally high central core, with two surrounding 

structurally high areas; an inner and an outer rim. The total deformed area is about 

65 square km; the central core area is 2.6 square km. Production is primarily from 

reservoirs in the central core that consist of highly deformed carbonate strata of the 

Upper Mississippian Madison/Mission Canyon Formation. Production occurs from 

highly fractured strata with less than 1 mD of permeability. Geochemical analyses of 

the oil indicate the source rock as the underlying Devonian Bakken Shale. 

Regionally, the Upper Mississippian Madison Group consists, at the base, of the 

Lodgepole Formation, overlain by Mission Canyon, overlain by anhydrite and salt of 

the Charles Formation, overlain by the Kibbey Formation (sandstones, shales, and 

carbonates). However, within the crater, these strata are of variable thickness and 

not present everywhere. 

At the peak of the central core, the steeply dipping vertical Mission Canyon 

strata are overlain by sub-horizontal Jurassic strata. The remainder of central core 

consists of steeply dipping Mission Canyon strata overlain by salt and anhydrite of the 

Charles Formation that fl owed after deformation. In the inner rim, the Mission Canyon 

Formation varies from gentle to steep dips (up to 22 degrees) and is overlain by the 

Charles Formation. The Mission Canyon strata in the outer rim are gently dipping (4-5 

degrees), and are also overlain by the Charles Formation. 

Interpretation of a 3-D seismic data set using select attributes allows for the 

detailed mapping of the faults and deformed strata within the impact feature. A 

combination of coherency, curvature, edge stacking, and dip azimuth attributes were 

used iteratively to determine the best interpretation. These attributes indicate that 

faults deform primarily the outer and inner rims, and the central core. The outer rim 

has a radius of 3.3 to 5 km (2 to 2.5 miles), and is defi ned by a series of arcuate 

normal faults, which are, in essence, an updip slide escarpment. Individual faults 

are up to 2.5 km (1.55 miles) in length with offsets up to 110 m (350 feet). The inner 

rim has a radius of 2 km (1.25 miles). Along the inner rim, faults have normal to high 

angle reverse motion with offsets up to 135 m (440 feet). Faults are up to 1.6 km 

(1 mile) in length. Faulting density is greatest in the central core. Faults are up to 

0.8 km (0.5 mile) in length, and have a radial to crosscutting pattern within the core. 

The decollement for the deformed Upper Mississippian interval appears to be the 

Lodgepole Limestone, directly underlying the Mission Canyon Formation. Attribute 

analyses also show fracturing/faulting of the Lower Paleozoic strata (about 1220 m, 

4000 feet) underlying the impact feature into the upper portions of the Precambrian 

basement.

RMAG August Board of Directors Meeting 

By Jay Leaver, Secretary (GeoLeaver@aol.com) 

The Board of Directors met on August 19th in the 

conference room of the University Building. The next 

regularly-scheduled BOD meetings are to be at the 

same venue, at 4:00 p.m., on Wednesday September 

16, October 14, and November 18. These meetings are 

open to the membership. 

The meeting began with a report from Elmo Brown, 

who is coordinating the 2010 combined RMAG-COGA 

Meeting (July 7 – 10 2010, too bad I don’t have a 2010 

calendar, or I’d mark it down.) These biannual events 

have become real regional dynamos, with a lot of 

synergy between the two groups. Truth to tell, the COGAers 

outnumber the RMAG attendees by 2:1. The way 

the allocation of funds works, RMAG gets 100% of the 

revenue from a given ticket or exhibitor if the attendee or 

exhibitor mentions RMAG. COGA gets 100% if they don’t 

mention RMAG, and the groups split the revenue 50-50% 

in the event the poor lost soul can’t make up their mind 

and chooses both. So please remember to support RMAG 

when the time comes to sign up (and no choosing ‘Mad 

Magazine’ as home organization this time, Ned!) 

At this point in the Board Meeting, we stepped 

into Executive Session to discuss Service Awards, with 

an update by Tricia Beaver. These Executive Session 

Outtakes are closed to the general membership for 

reasons of confi dentiality. I have always supposed that if 

a member actually were to attend a Board meeting (note 

how I faithfully invite you all at the beginning of each 

of these columns), we’d ask them to step outside and 

admire the lobby wallpaper during Executive Session. So 

far, it hasn’t been an issue, but you never know, someone 

might show up sometime and it’s best we all know the 

procedure. 

Tricia and Elmo then left the Board to its lonely toils. 

We reviewed the Minutes from July, which true to his 

word the Secretary had provided within a day or two of 

each meeting. I was touched that both Sandi and Jim 

had read them and responded with editorial comments 

– not fl attering ones, mind you, but it’s the thought that 

counts in these things. Perhaps next month we’ll even 

approve them. 

After a discussion of the fi nancial report (we could 

really use a stimulus package, folks, so please alert 

your representative), we moved on to offi ce matters. 

Josh Robbins is back from his unexpected hospital visit, 

which is doubly good because Caitlyn has left RMAG and 

Sandi could really use a hand with all the registrants for 

the Unconventional Symposium. That particular event 

(September 14) has really taken off. There is some 

competition for the Keynote Speaker slot. I suggested 

the candidates mud-wrestle for the spot, but was told the 

Symposium won’t be quite that unconventional. Darn. 

As a fi nal note, there have been a couple of instances 

of people taking pictures of slides during RMAG Friday 

Luncheon talks. This is not good form, folks, and on 

behalf of the Board of Directors I am authorized to issue 

an Offi cial ‘Tsk-tsk’ to those responsible. Let’s not go 

getting all high-tech here. If you see a slide you like, honor 

the Speaker and ask for a copy directly and politely after 

the talk. Otherwise continue scribbling notes the old 

fashioned-way, please, with stylus and clay tablet.

Mountain Geologist Editor Recognized 

Barbara Luneau, having completed four years 

as volunteer Executive Editor for the Mountain 

Geologist journal, has stepped aside with the July 

2009 issue. Barbara worked with several co-authors 

during this time including Mark Longman, Susan 

Landon, and Lyn Cantor. Together with several 

special issue guest editors, they shepherded 66 

articles in 17 issues of the Mountain Geologist. 

Barbara’s attention and continued support of 

the Mountain Geologist demonstrates a quiet yet 

admirable diligence. Working with several co- and 

special editors, she read, re-read, found reviewers, 

corresponded with authors, and worked with the 

proofs and fi nal layouts on many more than the 

articles mentioned here. Considering all that 

she has contributed, her ongoing support for the 

Mountain Geologist is commendable. 

The Mountain Geologist strives to incorporate a 

variety of Rocky Mountain geology sub-disciplines. 

The regional journal particularly shines when 

focused on a special theme issue. Several of these 

were produced during Barbara’s tenure. These recent 

special theme issues, many with guest editor guidance, 

have been focused on the Boulder-Weld Coal Field 

(January 2009), the Eocene Green River Formation (April 

2007), Rocky Mountain Gas Reservoirs (July 2006), the 

Structural Geology of the Colorado Front Range (January 

2006), and Cretaceous Sand Body Geometries in the 

Piceance Basin area of NW Colorado (July 2005). 

Barbara Luneau, executive editor of the Mountain Geologist from 2005-2009, was 

presented with an RMAG map weight by new editors Joy Rosen-Mioduchowski (left) 

and Jeanette DuBois (right). 

Following Barbara’s example, the new editors are 

looking for good articles and special theme issues. 

Please consider the Mountain Geologist journal for your 

technical work or summary updates on issues in Rocky 

Mountain geology. Joy Rosen-Mioduchowski and Jeanette 

DuBois can be reached at joyrosenm@gmail.com or

Geologic Educational Resources are Now Available on the Internet 

By Elmo Brown 

Now that the school year has begun, teachers, 

students and geologic professionals who have been 

asked to make presentations to classes or civic groups 

are looking for resource material. In the last year, the 

AAPG has initiated two web resources to fi t the bill. One, 

developed by the AAPG’s Youth Education Activities 

committee (YEA) is specifi cally designed for classroom 

teachers and visiting professionals and is located on the 

AAPG website at http://www.aapg.org/k12resources/. 

This site not only has links to other internet resources but 

also contains a handbook, developed in coordination with 

AGI, for geologists visiting the classroom with activities and 

tips on how to make the best use of the geologist’s and 

student’s time. This webpage also includes information 

on Earth Science Week activities (this year it will be held 

during the week of October 11-17), AAPG Teacher of 

the Year information, a couple of virtual fi eld trips, and 

information about the Maps in Schools Project promoted 

by members of the Corpus Christi Geologic Society. If you 

haven’t heard, the goal of the Maps in Schools Project 

is to have a USGS geologic map in every school in the 

USA. Over 1300 maps have been donated to schools to 

date, with most maps donated in the coastal bend area 

of Texas. However, the project has branched out into a 

dozen other states but according to the website’s map, 

not yet including Colorado. If interested in donating maps 

in your area, check out the website. 

The other resource, petroleumgeology.org designed 

by the Public Outreach committee of the AAPG, is geared 

more to the general public with general information a 

nd links specifi c to the petroleum industry. The four 

subcategories, Petroleum Thru Time, World of Petroleum, 

Geology & Petroleum, and Petroleum Technology, contain 

short information bites for each designated topic and a 

list of internet resources that go into much more intricate 

detail. This site is great for fi nding websites that fully 

explain all of the aspects of the oil and gas business. 

As the site’s mission statement says, “This website is 

built and maintained by actual geologists, who want to 

share with you their passion for the Earth and what they 

do. They want to answer your questions about where oil 

actually comes from and share their role in exploring the 

wonders of our planet. Their goal is to help you better 

understand the history of oil and gas exploration and the 

role oil and gas plays in today’s world. Who better to talk 

about these topics than the very people who search for 

and discover oil and gas?” 

For those geologists who are passionate about their 

careers (and which ones are not!) and want to share 

their geologic knowledge with others, these two sites 

are a must see for resources usable in the classroom 

and civic arenas.

Looking for a place to publish? How about The Mountain Geologist? 

The Mountain Geologist is the quarterly journal of 

the Rocky Mountain Association of Geologists (RMAG), 

published since 1964. It circulates to the 2200-plus 

members of the RMAG and about 200 university libraries 

and industrial associates. 

A regionally oriented peer-reviewed publication, the 

Mountain Geologist focuses on the geology of the Rocky 

Mountain area of the U.S. and related topics from outside 

the region. The range of topics presented in Mountain 

Geologist articles covers almost every sub-discipline in 

the geosciences: stratigraphy, paleontology, structural 

geology, mining and petroleum geology, hydrogeology, 

geophysics, and geochemistry. Authors from industry and 

academia are represented equally. 

Authors should submit double-spaced manuscripts 

in accordance with the Mountain Geologist Style Guide 

(available online at rmag.org). Suitability questions or 

manuscripts should be sent to Joy Rosen-Mioduchowski 

at joyrosenm@gmail.com.
