The Middle PreclassicAchiote sherd is interesting and ifmore were found within the cave, it mightsuggest an early phase which has not yetbeen identified this close to El Naranjal.Unfortunately, a number of logistical constraintsprevented further surface collectionof the cave.Actun Tam Ha does not appear to havehosted a broad range of activities like thatof Actun Toh. It is conceivable that offeringsonce deposited in the cave have sincebeen looted but identifiable altars orshrines are conspicuously lacking. Thougha disproportionately high number of smallstalactites are present (suggesting culturalbreakage), the cave does not appear to havebeen a preferred location for speleothemremoval. This is likely due to the chamber’ssteep walls and high ceiling. Actun TamHa is indeed a grand cave and was no doubtvalued for its majestic pool and for its expansiveand inaccessible nature.Figure 4.4.1. Map of Akab Ch’en.4.4: AKAB CH’ENAkab Ch’en (“dark well”) lies withinthe ejido of San Francisco, but is locatedapproximately 2 km southwest of the communityof San Cosme. In antiquity, the cavewas likely associated with the site of SanCosme itself. The following description isthe result of a single trip to the cave in thespring of 1996. The cave was not selected for detailedinvestigation; however, it was plotted, sketch mapped,and photographed.DescriptionAkab Ch’en can be divided into three distinctzones or areas. The entrance zone is a circular sinkhole,approximately 25 m in diameter, with 5 m-highvertical to incurving walls. The floor of the sinkholeis reached via an artificially carved portal along itsnorthern wall. This portal connects the interior of thesinkhole with an adjacent topographic depression orgully (see figures 4.4.1, 4.4.2, and 4.4.3). A stairwayconsisting of six intact risers spans the short verticaldrop between the threshold of the portal and the floorof the sinkhole. This stairway is composed of largeFigure 4.4.2. Profile of Akab Ch’en.well-dressed blocks. The floor of the sinkhole is relativelylevel except for a low mound of breakdown atits center. The entrance zone is well lit and due to itstall trees and lush foliage, has an atrium-like quality.An alcove is located high within the wall of the sinkhole(just east of the portal) and inside sherds were observed.Along the southeastern periphery of the sinkholefloor, is the entrance to a steeply sloping chamber. Awell-preserved stairway descends into this twilightarea and ultimately arrives at the twin entrances tothe room below. The stairway consists of roughly- towell-dressed blocks, and reaches the bottom of thesloping chamber via three switchbacks. The entrancesat the basal landing of the stairway are essentially twoovoid portals, which are divided by a dripstone columnatop a flowstone mound (see figure 4.4.4). The southernportal, which appears to have been the preferred

At the landing, the stairway/pathbifurcates into two separate stairways—one passingthrough each of the two portals.The lower room of Akab Ch’en is characterizedby two small pools divided by a crude altar. The twopath/stairways leading from the twin entrances jointogether in front of the altar. This feature consists of1×2 m circular mound of stones placed atop a flowstoneslope. A dripstone column and a drapery formationflank the altar and the flowstone slope. Two short pathsdiverge in front of the altar, each one leading to separatepools. At the edge of the larger of the two pools(which measures approximately 5×7 m, and .5 m deep)is a submerged step or landing which may have facilitatedwater collection when levels were periodicallylower. The smaller pool to the southwest is located ina tiny alcove and contains a semi-circular stone featureon its floor. Both pools are permanent and markthe current water table (which in this area is roughly20m below the ground surface).Though sherds are scattered across the lower room(including the floors of the two pools), no discreteofferings or whole vessels were observed. Access tothe cave is easy and the lower room appears to beheavily trafficked. My guide informed me that localhunters often use the cave as a source of drinking waterwhile out in the bush, and modern bottles were foundedstashed near the pools. If any whole vessels or artifactswere deposited in the cave, they have no doubtbeen removed. Like most of the caves in the survey,evidence of speleothem breakage and removalis present. No intact large speleothemswere observed and soda straws grow frommany of the stumps on the ceiling.A number of structures were observedin the immediate vicinity of Akab Ch’en,and likely corresponded to the site of SanCosme. A square platform (25 m on a side)with well-preserved Megalithic masonry islocated 15 m east of the edge of the sinkhole.At least six substantial residentialplatforms were identified within 75–100m of Akab Ch’en. No wells were found inthe area. However, two small aguadas(which appear to have been carved into thebedrock) were found near the mounds.Figure 4.4.4. Entrance to lower room of Akab Ch’en.
