No bone tools, stone tools, distinct cut marks,
or charcoal have been observed at the Coldwater locality. One amateur paleontologist reported the discovery of
a single human bone
from the Coldwater locality; the bone is human, but it is unlikely that it is contemporaneous with the Ice Age deposit.
The context of the single human bone was documented (measured, drawn, photographed, etc.) when it was discovered.
The Coldwater locality has been studied for over 30 years by
Dr. Bruce Stinchcomb, retired Professor of Geology at St. Louis Community College at Florissant Valley. The digital images
at this website are of animal and plant samples collection by Professor Stinchcomb.
