About this map

Mining operations and high-desert terrain define this area of the Cherry Creek Range and the Egan Range in the early 1980s. The landscape is marked by numerous extraction sites, including the Gilligan Shaft, San Jose Tunnel, and several family-named prospects like the Joanna Mine and Jonny Mine. These workings cluster around Egan Canyon, where the Egan (Site) settlement is noted along the banks of Egan Creek.

To the east, the terrain drops into the Steptoe Valley, where the Johnson Ranch sits near a network of irrigation ditches. To the south, the Egan Basin provides a natural corridor between the mountains, leading toward Ninemile and Ninemile Springs. The map reveals a transition from the industrial legacy of the Old Borchert Mine and Black Sheep Mine to the remote ranching and grazing lands that characterize this part of White Pine County.
