About this map

The Snake River carves through this Owyhee County landscape, serving as the border between Elmore and Owyhee counties. The map documents a critical corridor of western transit, showing the Old Mountain City Freight Trail and the Emigrant Trail navigating the difficult terrain near the riverbanks. Riverside features like Wilkins Island and Blacks I sit within the channel, while the Loveridge Bridge provides one of the few crossings in the area.

Away from the water, the geography is defined by the shifting Sand Dunes and the broad depression of Eagle Cove. Topographic details from the late 1940s highlight the isolation of the high desert, punctuated only by landmarks like Flatiron Butte and the remote Barber Cabin. This survey captures the region before extensive modern development, preserving the routes of freight haulers and pioneers through the gulches and springs of the Idaho desert.
