Hailey and Ketchum serve as the primary hubs in this late nineteenth-century survey, connected by the Union Pacific (Wood River Branch) R. R. through the Wood River valley. The map documents a landscape defined by significant peaks and thermal features, such as Guyer Hot Springs and a second Hot Springs site to the south. The drainage patterns are intricate, with the North Fork Wood River and Lost River systems carved into the high terrain. High-elevation landmarks like Hyndman Peak and the curiously named The Devils Bedstead dominate the eastern horizon. The presence of early settlements like Gimlet and numerous gulches and creeks—such as Ohio Gulch and Warm Springs Creek—suggests a region shaped by both its geology and the early mining and transportation routes that followed these natural corridors. This record provides an exact view of the Custer Co. Blaine Co. boundary as it was formally established during this era.
