| has gloss | eng: The Chuska Mountains are an elongate range on the Colorado Plateau and within the Navajo Nation. The range is about 80 by 15 km (50 by 10 miles), and it trends north-northwest and is crossed by the state line between Arizona and New Mexico. The highlands are a dissected plateau, with an average elevation of about 2700 meters (about 8900 feet), and subdued topography. The highest point is Roof Butte (36.4601° N, 109.0929° W) at 2994 meters (9823 feet), near the northern end of the range in Arizona. Other high points include the satellite Beautiful Mountain at 2861 meters (9388 feet) and Lukachukai Mountains at 2885 meters (9466 feet), both also near the northern end, and Matthews Peak at 2911 meters (9550 feet). The San Juan Basin borders the Chuskas on the east, and typical elevations in nearby parts of that basin are near 1800 meters (about 5900 feet). The eastern escarpment of the mountains is marked by slumps and landslides that extend out onto the western margin of the San Juan Basin. To the north, the Chuskas are separated from the Carrizo Mountains by Red Rock Valley. |
