Sometime around 1900, the Atchison, Topeka and Santa Fe Railroad (AT&SF) was putting together a "cut-off" at Belen, New Mexico, for routing freight trains either east or west. A newspaper man from Winfield Kansas, John W. Corbett, learned that the easterly tracks would likely pass through Abo Pass in New Mexico. Therefore, he and a friend, Colonel E. C. Manning, decided to locate a townsite at the top of the Pass. The cool summer breezes off the Pass resulted in naming their new community, "Mountainair".
