1967 Map of Grassy Mtn

USGS Topo · Published 1971

About this map

Grassy Mountain anchors this high-desert landscape in Malheur County, where 1960s ranching and water management are clearly evident through a network of springs and reservoirs. The terrain is defined by rugged volcanic formations such as Shell Rock Butte and Haystack Rock, interspersed with isolated water sources like Lowe Spring and Mendiola Spring. These named springs, often the only reliable water for miles, indicate the vital points of human and livestock activity in the arid basin.
