BartlettPic4View towards the south of the north slope of Clinch Mountain, the crest of which marks the division line between Washington (southward) and Russell Counties. The recovery site was in a deep trench just beyond the large tree on the right. The grassy field behind that tree is underlain by a massive debris flow that originated in the valley to the left of this picture and filled in the mouth of the valley with the trench. A series of extremely large torrential rain storms that passed across this mountain in the past 40,000+ years built this debris fan which clogged the small valley and created ponds and wetlands that preserved the mastodon and mammoth bones

BartlettPic1View of the 29 foot-deep trench dug with a very large backhoe in preparation for constructing a dam for a trout pond on this land where the extinct animal bones were recovered. Four radio-carbon dates were obtained from wood extracted in the lower five feet of the trench and ranged from 29,100 +/- 300 B.P. years to 32,400 +/- 480 B.P. years
