Eleven national forests in Arizona and New Mexico and two national grasslands in New Mexico, Texas, and Oklahoma make up the Southwestern Region of the U.S. Forest Service. With elevations ranging from 1,300 feet in the Sonoran Desert on the Tonto National Forest to 13,161 feet in the alpine tundra of Wheeler Peak on the Carson National Forest, the vegetation is extremely varied and the wildflower viewing opportunities are tremendous!
