About this map

The Owens River and the expansive Tinemaha Reservoir dominate this Owens Valley landscape, showing a complex water management and transportation network in the early 1990s. The reservoir is defined by its levee and Outlet Tower, while the nearby Old Railroad Grade traces the legacy of former rail infrastructure through the valley floor. To the east, the terrain rises sharply into the Inyo National Forest and Harkless Flat, marked by a history of extraction including the Montezuma Mine and Blake Mine.

Geological features such as the Poverty Hills and vast fields of Lava contrast with the riparian corridor of Sangers Slough. Named points of interest for local historians include the small rises of Charlie Butte and the hydrologic sites at Big Seeley Spring and Little Seeley Spring. This 1990 photo-inspected survey also documents several industrial sites like the Mule Spring Quarry and the New Era Mine on the mountain slopes.
