The document describes an environmental living program where students stay overnight at Yosemite National Park and assume the roles of historical figures to perform tasks from the 19th-20th centuries like chopping wood and blacksmithing. The main focus is on the history of land management in Yosemite and how current land use issues are similar to those in the past. Students will discuss and experience firsthand what life was like for pioneers to better understand land use decisions over time.
