Williamson-Abbot Expedition Ponderosa
Posted on: February 17th, 2025 in Heritage Tree Details |

Pinus ponderosa
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.
