1987 Map of Eaglenest Basin

About this map

Heart Mountain dominates the western landscape of this Wyoming terrain, where the high slopes descend toward the irrigation-fed reaches of Ralston Flats. This 1980s provisional survey documents the intricate water management infrastructure essential to the region, most notably the Heart Mountain Canal and the Ralston Lateral which traverse the basin's eastern edge. An Aqueduct system further highlights the engineering efforts to move water through this arid environment. The map details a complex drainage network including South Eaglenest Creek and Buck Creek, which carve through the Eaglenest Basin. For researchers, the presence of family-named landmarks like Idaho Creek and the remote Buck Springs provides specific geographic markers in a territory defined by its hydrological modifications and dramatic elevation shifts.
