2021 Map of Eaglenest Basin

About this map

Heart Mtn dominates the southwestern corner of this landscape, where the terrain falls away toward the intricate drainage networks of Eaglenest Basin. The land here is defined by a sophisticated water management system designed to support agriculture in this high-desert environment. The presence of the Heart Mountain Canal, along with specialized irrigation features like Lateral H-105 and Lateral H-89, reveals the engineering required to move water across the Ralston Flats. Numerous seasonal watercourses, including S Eaglenest Cr, Buck Springs Cr, and Question Cr, carve through the basin, illustrating the natural watershed that precedes the irrigation works. Near the northern boundary, the Alkali Cr Reservoir and various road segments like Rattler Rd and Canal Rd further mark the intersection of natural topography and human infrastructure in Park County.
