Rio Grande National Forest
The Rio Grande National Forest (NF) is 1.86 million acres located in southwestern Colorado and remains one of the true undiscovered jewels of Colorado. The Continental Divide runs for 236 miles along most of the western border of the Forest. The Forest presents myriad ecosystems; from 7600-ft alpine desert to over 14,300-ft in the majestic Sangre de Cristo Wilderness on the eastern side. The Forest embraces the San Luis Valley, the largest agricultural alpine valley in the world and includes all or parts of four Wilderness Areas (South San Juan, Weminuche, La Garita and Sangre de Cristo). The Forest also is the headwaters of the Rio Grande River and has the moonscape wonder of the Wheeler Geologic Area, established by Theodore Roosevelt in 1911. The Anasazi were visitors here and many of their sites remain.
