Inscription.  Unlike the shallow bank exposed at University Hill, this end of the waterhole had a steep bank about three feet high. Here in the deeper part of the waterhole, thick deposits of undisturbed bones were found, including about twenty chalicotheres excavated by the American Museum of Natural History.

Juveniles, young adults, older females, and large adult males were discovered together at this edge of the waterhole, some largely intact, suggesting a small herd that died at the waterhole at one time. Bones at the periphery of the waterhole, on the other hand, were found in a single layer and were widely scattered by scavenging animals.
