The Fremont-Winema National Forest of south central Oregon is a mountainous region with a rich geological, ecological, archaeological, and historical history. Founded in 1908, the Fremont National Forest was originally protected as the Goose Lake Forest Reserve in 1906. The name was soon changed to Fremont National Forest, named after John C. Frémont, who explored the area for the United States Army Corps of Engineers in 1843. In 2002, it was administratively combined with the Winema National Forest as the Fremont–Winema National Forests. The volcanoes of the Fremont Forest are typically older than the Cascades and were a result of tectonic shearing stretching the crust thin which allowed mantle magma to emerge at the surface. Crustal stretching continued through the late Miocene resulting in uplifted fault blocking of what was flat basalt landscapes, creating into towering scarp- mountains that are gently sloped on one side and terminate into a sharp scarp face on the other. The east portion of the Fremont Forest region is like this, sloping to the west and terminating in a sheer scarp face along the Summer Lake sub-basin. source wikipedia. prints available. see more at www.footeprintart.com
