1954 Map of Pearsoll Peak

About this map

The Siskiyou Mountains define the character of this mid-century survey along the border of Curry and Josephine counties. Remote mining operations and isolated ranching outposts are the primary signs of habitation, with several extraction sites like the Old Glory Mine, Robertson Mine, and Chrome King Mine scattered across the high terrain. The drainage of the Illinois River serves as the central artery for the landscape, marked by river mile indicators and rugged tributaries including Indigo Creek and Briggs Creek. Land use is further evidenced by a network of lookouts and administrative sites, from the Silver Peak Lookout to the Store Gulch Guard Station. Named prairies and flats, such as Silver Prairie and Sourdough Flat, break the mountain peaks, suggesting areas of historical grazing or small-scale settlement like the Fantz Ranch and McCaleb Ranch.
