1987 Map of Mount Holmes

About this map

Mount Holmes stands as the central landmark in this high-desert landscape within the Henry Mountains and the Little Rockies. This 1980s-era topographic study reveals a land shaped by deep drainages, including Fourmile Canyon, Twomile Canyon, and Woodruff Canyon, all cutting toward the eastern boundary of the Glen Canyon National Recreation Area. Human activity is marked by scattered infrastructure, including an unnamed mine and adits located near Star Benches, and a series of 4WD tracks that provide access through the complex terrain. The map details vital water sources in an otherwise arid environment, such as Woodruff Spring and Hole Spring, which anchor the northern reaches near Woodruff Hole. To the east, the distinctive Hoskinnini Monument rises near the edge of Trachyte Creek, marking a significant geological feature on the canyon's rim.
