1952 Map of Spyrock

USGS Topo · Published 1954

About this map

Round Valley Indian Reservation dominates the landscape of this mid-century survey, with the town of Covelo serving as a focal point in the broad valley floor. The Eel River and its North Fork carve deep canyons through the mountainous terrain, followed closely by the winding route of the Northwestern Pacific railroad. Small, isolated settlements like Nashmead, Spyrock, and Mina are positioned at intervals along the rail line and river, marking important transit points for the remote ranching and timber country. Higher elevations are characterized by significant landmarks such as Updegraff Ridge and Pookkinny Ridge, while early educational infrastructure is represented by the remote Lake Mtn Sch. The map records a complex network of creeks, including Shell Rock Creek and Woodman Creek, that define the drainage basins of the Mendocino and Trinity county borderlands.
