About this map

Fish Lake Valley straddles the California and Nevada border, where high-altitude research and ranching met in the mid-20th century. High peaks of the Inyo National Forest dominate the western terrain, featuring the White Mtn Research Sta Barcroft Laboratory (Univ of Calif) near Mt Barcroft. This remote environment is also home to the Ancient Bristlecone Pine Area, where the noted Patriarch Tree stands as a landmark of natural longevity.

Down in the valley, the Von Schmidt Line Boundary marks the historic border division passing through a landscape of working ranches like Circle L Ranch and McAfee Ranch. Small-scale settlements are anchored by the Dyer PO and Dyer Sch, while the presence of the Green Monster Mine and Eva Belle Mine points to the region's mining heritage. These features together show a sparsely populated high-desert frontier defined by scientific inquiry and traditional livestock operations.
