|STS058-090-015 Rocky Mountains, North-Central New Mexico, U.S.A. October 1993
The forested mountains and dry intermontane valleys of this portion of the Rocky Mountains in north-central New Mexico are shown in this low-oblique, west-looking photograph. Apparent are the headwaters of the Purgatoire River and many tributary streams that originate in the massive, north-south-trending, forested Sangre de Cristo Mountains (lower right corner) and the Canadian River (lower left corner). The southern extension of the San Luis Valley, part of the Rio Grande Rift that extends north-south through New Mexico, separates the slopes of the Sangre de Cristo Mountains to the east from the San Juan Mountains to the west. West of the San Juan Mountains appears the large, dry San Juan River Basin, with the Chuska Mountains to its west. Most of the circular, dark features are volcanic remnants.
