We can only guess what human activity has occurred on this mountainside over the centuries but there are clues. Artifacts (arrowheads, Indian beads, pottery shards and a pink glass ink well) have been found on this land. The area has been known for years to have significant wildlife including deer, bear, raccoon and bobcat. We know the Old Santa Fe Trail passed on the other side of the hill. One of the several trails between Santa Fe, Pecos and Las Vegas is now the Old Las Vegas Highway. It has been known as the Pecos Trail, the Old Denver Highway, U.S. Route 66 and now Old Las Vegas Highway. It was part of U.S. Route 66, between Chicago and Los Angeles from 1926 to 1937.  In 1937, New Mexico Governor Hannett, for political reasons, ordered a road to be built from Santa Rosa direct to Moriarty, by passing Santa Fe. This rerouting of Route 66 shortened the distance between Santa Rosa and Albuquerque by 90 miles.

In 1985, this subdivision was incorporated by Calimo, Inc. One of the main partners was from California and the other was from Missouri, hence "Cali" and  "mo". Its first Board of Directors consisted of principals in the corporation. Its first Board of Directors consisted of principals in the corporation. The first two families, Bertins and Chaloms, moved into the subdivision in 1989. In 1990, at the first meeting of members, Mark Chalom was elected to the Board. The other two officeholders were corporate owners.

With the appointment of Richard Johnson to the Board in 1991, homeowners assumed control of the association with one developer remaining on the Board. From 1992 to present all Board members are homeowners.

Old Pecos Trail Estates is a beautiful place! The Board of Directors encourages your continued support, contribution and participation.
