During the routine construction of a stock pond in 1962 near Worland, Wyo., Donald Colby uncovered a Clovis projectile point. In so doing, he found some of the earliest known evidence of human activity in Wyoming, dating to more than 11,000 years ago. Mammoth remains were discovered at the site as early as 1907, but beginning in 1973, a team of archaeologists led by Wyoming State Archaeologist George Frison, began investigating Colby’s find.
Frison’s team found a total of 463 bones concentrated in two piles in a prehistoric arroyo, along with several stone and bone artifacts. Among the bones were the remains of at least seven mammoths. Although some of the bones were disturbed, Frison and other researchers believe that the bone piles were the remains of meat caches. This find provides a unique glimpse into the life of the first hunters and gatherers of Wyoming.
