Straddling Peters Mountain, the 803-acre Joseph E. Ibberson Conservation Area is dominated by large hardwood trees. This large block of nearly unbroken forest is a haven for wildlife like forest warblers and other deep-woods animals. A main attraction to the conservation area is the elaborate trail system that connects to the Appalachian Trail.
The land of the conservation area has been inhabited for over 11,000 years. The nearby Shoop Site is one of the largest and oldest Paleo-Indian sites in eastern North America. The Shoop Site is unusual in that it is near a hilltop and not like most Paleo-Indian sites in the floodplain. Archaeologists theorize that the Paleo-Indians were hunting migrating caribou. It is interesting that most of the stone tools found at the site were made from stone found 250 miles north in New York.
Subsequent inhabitants used the Shoop Site as a temporary shelter or hunting camp. Other Indians occupying or passing through the area were the Shawnee, Nanticoke, Lenni Lenape and Iroquois League of Six Nations. The Susquehannock Indians claimed the land at the time European settlers arrived at Peters Mountain and Powells Valley.
Thousands of artifacts from the Shoop site are exhibited in the Smithsonian Institution and the Pennsylvania State Museum. The Shoop Site is on private land and is not open to the collecting of artifacts.
