2017 Map of Eaglenest Basin

About this map

Heart Mtn dominates the southwestern corner of this high-desert landscape in Park County, where the terrain drops away into the namesake Eaglenest Basin. This 2017 study illustrates the complex irrigation network vital to the region's agricultural viability, featuring the primary Heart Mountain Canal alongside numerous lateral lines like Lateral H-105 and Lateral H-80. The map documents a rugged drainage system where ephemeral streams such as Buck Springs Cr, Iron Cr, and Question Cr carve through the arid benches. To the northeast, the land levels out toward the Ralston Flats, while the presence of the Alkali Cr Reservoir highlights the managed water resources essential for maintaining life and industry in the shadow of the Absaroka Range foothills.
