1986 Map of Latham Spring

About this map

Targhee National Forest defines this high-country terrain on the border of Fremont County, Idaho, and Gallatin County, Montana. The landscape is a network of watercourses, where the North Fork, Middle Fork, and South Fork join other drainage systems like Chick Creek and Moose Creek. A prominent Trail serves as the primary human mark in this wilderness, navigating the complex topography near Split Creek and Lucky Dog Cr. This 1980s-era survey emphasizes the hydrological intersections and elevation patterns before modern development. One notable feature, Latham Spring, stands as a critical water source in an area otherwise characterized by deep-cut features such as the Thirsty Black Creek Canyon. The map records a moment of transition between these two states, capturing the undeveloped character of the forest's interior.
