Glade Mountain and Thomas Mountain anchor this high-elevation landscape in Dolores County, where a complex network of water management features reveals the critical role of irrigation and storage in the American West. The map shows a series of numbered reservoirs along Disappointment Creek and its tributaries, including Disappointment Number Nine Reservoir and Disappointment Number Two Reservoir, indicating a highly organized system of water rights and land use. This infrastructure supports the surrounding terrain of The Glade and The Hogback. Resource extraction is evidenced by the Broken Thumb Mine near the center of the sheet, while navigational aids like Benchmark Lookout serve as vital points in this remote terrain. Numerous springs and draws, such as Bradfield Spring and McKinney Draw, feed the network of basins that define the local ranching or agricultural economy of the early 21st century.
