Tip Top Mountain and the high elevations of the Bighorn Mountains dominate this high-desert landscape within the San Bernardino National Forest. The geography is defined by a critical network of water sources, including Rattlesnake Spring, Two Hole Spring, One Hole Spring, and Mound Spring, which were vital for early travel and survival in this arid environment. The map records a history of prospecting with numerous prospects and mines scattered across the slopes and canyon floors, particularly near Rattlesnake Canyon. This 1990s revision reflects a balance between historical land use and modern conservation, showing the designated Bighorn Mountain Wilderness Boundary. Notable landmarks like Granite Peaks and the Communication Facility atop the peaks provide orientation points above the drainage of Arrastre Creek and the expanse of Lone Valley.
