1966 Map of O'Leary Peak

About this map

Volcanic geology and high-desert water management define this portion of the Coconino National Forest in the mid-1960s. The landscape is dominated by the massive San Francisco Mountain and the distinct volcanic features of Robinson Crater and Darton Dome. Along the southern margin, the Bonito Lava Flow encroaches into the Sunset Crater National Monument, showing the stark geological boundaries of the region. Human presence is sparse, centered on the Espil Ranch and the Sacred Mtn Trading Post along Route 89. A sophisticated network of livestock tanks, such as Chavez Tank and Old Grand Canyon Tank, underscores the critical importance of water in the Sinagua Valley and across the broad Deadman Flat. The O'Leary Peak Lookout Tower stands as a sentinel over the vast stands of timber and the deeply incised Deadman Wash.
