Alamocita, initially called New Alamosa, was a later 19th century native New Mexican frontier settlement along the east bank of the Rio Grande and is now a ghost town in Sierra County, New Mexico, United States.
Alamocita also was six miles north of Fort McRae, established in April 1863 to protect these new settlements along the Rio Grande from the Apache, along with the traffic along the river and the old road to the east in the Jornada del Muerto.
Twenty miles south of Fort McRae, it was less exposed to the attacks of the Apache, and there they established the settlement at first called Plaza del Rio Palomas.
Fort McRae and its garrison would provide its protection, arms and economic benefits to citizens of the towns over the years of its operation until it was closed on October 30, 1876.
[2] Alamocita ceased to be a town in 1880, following a flood that changed the course of the Rio Grande, washing away or leaving most of the irrigatable lands on the west bank of the river.
