1967 Map of Jackass Butte

About this map

Malheur National Wildlife Refuge dominates the northeastern corner of this high-desert landscape, where the Buena Vista Canal and Buena Vista Lake create a critical riparian contrast to the surrounding arid terrain. The map documents the dramatic topography of Harney County, specifically the massive uplift of Jackass Mountain and the steep escarpment of the Black Rim. Remote outposts like Juniper Park Ranch and a lonely Corral indicate the ranching heritage of the Blitzen Valley. Navigated primarily by a network of Jeep Trails, the area is defined by its stark geological formations, including the prominent Jackass Butte and numerous seasonally dry basins labeled as Alkali Flat. This survey provides a precise look at the drainage patterns and relief that dictated land use in this sparsely populated region during the late 1960s.
