Copco Dam anchors the northern edge of this survey, where it impounds the Klamath River to form Copco Lake. Surveyed in 1922 by C.A. Stonesifer, this sheet captures a landscape defined by dramatic elevation changes along the river's path through Siskiyou County. The detailed five-foot contour intervals reveal the intricate topography surrounding the reservoir, an engineering focus for the U.S. Reclamation Service and the Klamath-Shasta Valley Irrigation District. A lone School is marked on the eastern side of the terrain, providing a small trace of early 20th-century rural settlement amidst the heavy technical contouring of the valley.
