TeamworkPreserves Mound at ToltecAgencies Provide Materials, Tools <strong>and</strong> People PowerBy Jeff WilliamsToltec Archeological StatePark SuperintendentStewart Carlton hefts a rollof coconut matting to helpcover the base of Mound P.Photo by Jeff Williams.Not much is obvious at Toltec Mounds Archeological State Park – even the name is a misnomer. Severalancient mounds dominate the surface, but much of what makes this ground intriguing is buried.Park Superintendent Stewart Carlton says 19 mounds have been identified, <strong>and</strong> excavations as recent as2010 have helped piece together the lives of people who lived here from about 650 through 1050.The park lies along Mound Pond, an <strong>Arkansas</strong> River oxbow, in western Lonoke County. Several stateagencies recently created a partnership because water in the lake was eroding part of Mound P, one of thepark’s smaller mounds. Erosion was exposing artifacts such as arrowheads <strong>and</strong> pipes, <strong>and</strong> eventually thewater would create irreparable damage to the site.The problem arose from Mound Pond’s fluctuating water level. Since homes have been built across thelake from the pond, the water level tends to be higher on average than it was for years, which means wavesslap the base of the mound.16ARKANSAS WILDLIFE NOVEMBER • DECEMBER 2011
“These mounds were built a bucket of dirt at a time,” Carltonsaid. “They’re not really solid <strong>and</strong> they erode very easily.”That’s why a crew of 12 got together in summer heat fora work day. The <strong>Arkansas</strong> <strong>Game</strong> <strong>and</strong> <strong>Fish</strong> <strong>Commission</strong>, the<strong>Arkansas</strong> Archeological Survey, the <strong>Arkansas</strong> ArcheologicalAssociation, the Natural Resources Conservation Service <strong>and</strong><strong>Arkansas</strong> State Parks pitched in with tools, materials <strong>and</strong> peoplepower. The individuals brought expertise in biology, archeology,conservation, interpretation <strong>and</strong> probably a few other areas.A section of lakeshore about 50 feet long needed protection.Coconut matting – it looks like burlap on a carpet roll – wassecured along the steep bank to keep wave action from digginginto the fragile dirt. At the bottom of the matting, nearest thewater, logs were anchored with steel cables so they wouldn’t floataway with changing tides.“The idea (of using logs) came from a tree falling naturally<strong>and</strong> the earth behind it not eroding as easily,” said Steve Filipek,assistant chief of the AGFC <strong>Fish</strong>eries Division. “The mat takesaway the power of water washing against the ground. We’llplant some things like white clover <strong>and</strong> river cane to help hold ittogether. It will have a very natural look from the lake.”The coconut mat also becomes good mulch as it deteriorates<strong>and</strong> plants begin to grow. These techniques <strong>and</strong> others are usedby the AGFC’s Stream Teams across the state to stabilize <strong>and</strong>restore river banks.It’s a simple but time-consuming <strong>and</strong> withering task. Woodenstakes are pounded through the mat to hold it in place. Theheavy logs are toted by h<strong>and</strong> <strong>and</strong> the cables that secure them areanchored through roots <strong>and</strong> rocks. It’s a hot, sweaty, bug-infestedproduction.But maintaining the site is worth the effort.Toltec Mounds, a National Historic L<strong>and</strong>mark, was named bythe owner of the property in the 1800s who thought Toltecs fromMexico built the mounds. Research later revealed these moundswere part of the Plum Bayou Culture, people who lived alongthe rivers of eastern <strong>and</strong> central <strong>Arkansas</strong>. Toltec Mounds is thelargest Plum Bayou site.Some of the mounds at Toltec are low <strong>and</strong> hard to recognize.“These mounds were probably not much bigger than they arenow,” said Elizabeth Horton, a paleoethnobotonist with theUniversity of <strong>Arkansas</strong> Archeology Survey, based at the ToltecMounds Research Station, as she stood at Mound P.Farmers over the years pulled apart mounds across the region.Although not all mounds were as majestic as the Toltec examples,they were plentiful.“We have some interesting surveys in the 1800s <strong>and</strong> sketchesthat show the mounds,” Horton said.Toltec holds the largest American Indian mounds in<strong>Arkansas</strong>. They were surrounded by a dirt embankment 8-10 feethigh, part of which remains. The mounds <strong>and</strong> wall were part of acomplex where ceremonies were held <strong>and</strong> business conducted.For more information about the park, visit www.arkansasstateparks.com/toltecmounds or call 501-961-9442.
