From the northern peaks of the Rocky Mountains all the way to the southern Chihuahuan Desert, the regional office serving the Department of Interior Regions 6, 7, and 8 includes 85 park units within eight states of the American West. These regions span the states of Texas, Oklahoma, New Mexico, Colorado, Utah, Wyoming, Arizona, and portions of Montana (in Regions 5 and 9) making the size of the region larger than the size of the Louisiana Purchase of 1803. With around 11.2 million acres of public land, the region hosts over 57 million visitors annually.
The region employs approximately 5,700 people and hosts more than 25,500 volunteers during peak travel seasons. The regional office is located in Lakewood, Colorado, with remote offices in Santa Fe, New Mexico; Phoenix, Arizona; and Tucson, Arizona.
