1949 Map of Sinker Butte

USGS Topo · Published 1949

About this map

The Snake River carves a deep canyon along the eastern edge of this late-1940s survey, marking the boundary between Ada and Owyhee counties. This landscape is a corridor of transit and conflict, anchored by the Emigrant Trail winding across the high desert terrain toward the river. Near the confluence of Sinker Creek and the Snake, the map identifies the Otter Massacre Site and Jacob Reuben Graves, poignant reminders of the perils faced by travelers on these routes. Local industry is represented by the Power Plant at Swan Falls, while the interior of the quadrangle shows the sparse settlement pattern of the era through the isolated Gabica Ranch and Montini Ranch. Countless wells and several springs are mapped across the arid landscape, highlighting the critical importance of water resources in the shadows of the prominent Sinker Butte.
