Rio Grande National Forest is a 1.86 million-acre (7,530 km²) [1] U.S. National Forest located in southwestern Colorado. The forest encompasses the San Luis Valley, which is the world's largest agricultural alpine valley, as well as one of the world's largest high deserts located around mountains. The Rio Grande river rises in the forest, and the Continental Divide runs along most of its western border.[1] The forest lies in parts of nine counties. In descending order of land area within the forest they are Saguache, Mineral, Conejos, Rio Grande, Hinsdale, San Juan, Alamosa, Archuleta, and Custer counties. Forest headquarters are located in Monte Vista, Colorado. There are local ranger district offices in Del Norte, La Jara, and Saguache.[2]
