About this map

The Continental Divide dictates the rugged hydrology of this high-elevation landscape, where the waters of Homestake Reservoir and Turquoise Lake serve as anchors for a complex network of engineering. Beneath the high peaks, an extensive system of subterranean infrastructure is visible, including the Boustead Tunnel and Missouri Tunnel, alongside the Homestake Aqueduct and various intake and outlet works. These features illustrate the mid-20th-century efforts to manage water across the divide.

Legacy mining and transportation routes mark the eastern slopes near St Kevin Gulch and Bartlett Gulch. Researchers can trace the path of the Old RR Grade climbing toward Hagerman Pass, passing near the historic Hagerman Tunnel. The area is dotted with evidence of hard-rock exploration, from the Grandview Shaft and St Kevin Shaft to several specialized boreholes like the Wilkes Barre Tunnels and Griffin Tunnels, reflecting the industrial persistence required to work these alpine elevations.
