The rockshelter was periodically used beginning about 8150 years ago although there are few times that it was more heavily used than others. The heaviest use based on the numbers of spear points and big game animal bones is about 2000 years ago; and the second most heavily used time was the initial use of the site at about 8150 years ago. After about 2000 years ago the sediments that were collecting in the shelter had become so deep that there remained very little area protected from the elements.
