Indigenous peoples have cared for and cultivated the ancient pine forests in this area since time immemorial. In 1855, the Williamson-Abbot Expedition camped here while surveying the Deschutes Basin for possible railway routes, utilizing existing Native American trails. While encamped here during that expedition, Lt. Phillip Sheridan carved his name and the date into this old growth ponderosa pine. The tree has since healed over the carving.
Location: Whispering Pine Horse Camp, 10 miles west of Sisters off Trout Creek Butte Rd. Located in public campground.
