Who Created the Southern Rockies Region With These States

It may sound like someone is coming on here sounding like an expert of the Southern Rockies or some stuff like that, but it is not my intention. It just so happens I make my living that includes geography. Last time I looked, Nebraska and Kansas were not in any kind of the Rocky Mountain Region but were in the mid-west and plains states. I'm just sayin. Anyhow, New Mexico and northern Arizona not only are in the Southwest Region, but also are on the southern tip of the Rocky Mountains, and included in the Southern Rockies. Just wanted to watch this board and see what folks are up to in Colorado and other areas of this region. Oh yes, last time I looked and lived there, Wyoming was part of the northern rockies.

Just keepin it real
