1966 Map of Barrel Springs

About this map

Barrel Springs and the surrounding high desert terrain define this transition zone where the borders of Nevada, Oregon, and California converge. Mapped in the mid-1960s, the landscape is marked by a network of intermittent water sources and ephemeral drainage patterns, including Twelvemile Creek and the shallow basins of Twin Lakes. The presence of a Gravel Pit and numerous unpaved routes, labeled simply as Trail or Jeep, suggests a working landscape of resource extraction and rugged overland travel. This survey meticulously details the administrative boundaries of the tri-state area, documenting the intersecting lines of Washoe County, Lake County, and Modoc County during a period of minimal development in this corner of the Great Basin.
