(Wyoming - Idaho) Map of the Sources of the Snake River, with its Tributaries together with portions of the Madison and Yellow Stone principally the results from Observation during the Snake River Expedition reduced from the Preliminary Map after Surveys by Gustavas B. Bechler
This is an interesting map principally of the region west and south of the Grand Canyon of the Yellowstone. Fort Hall is in the SE corer and much of the Jackson Hole region is included as well. It is early, and unusual to find a map works at the detail of the region. Tackles the drainage as well as topography, and some land quality (“Undulating Table Land”)..
Condition is very good. Image size is approximately 11 x 10
