Physiographic maps or atlases will help discern the following landforms in this southeast-looking, synoptic photograph of the Rocky Mountains of southwest Colorado and north-central New Mexico. Viewing counterclockwise are the Front Range of the Rocky Mountains, Sangre de Cristo Mountains, Sawatch Range with the San Luis Valley to its south, San Juan Mountains, San Juan River Basin with sunlight reflected off the Navajo Reservoir, and the Uncompahgre Plateau and Gunnison River Valley with the Blue Mesa Reservoir to their east. Visible are snow cover on some of the higher elevations of the Rocky Mountains; the headwater areas for the Arkansas River and the Rio Grande; and a small section of the Great Plains (upper left corner).
