1991 Map of Belen SW

About this map

The Belen Grant dominates the eastern landscape of this New Mexico quadrangle, where the Rio Puerco flows through a terrain defined by complex drainage networks. This 1991 revision, based on much earlier imagery, illustrates an arid expanse where the New Mexico Principal Meridian serves as a critical survey anchor. The land is carved by numerous dry watercourses including Arroyo Monte Belen, Arroyo Comanche, and Arroyo Alamito, which cut through the high ground of Montano Flats. The mapping reveals a sparse network of 4wd trails, indicating the limited human infrastructure in this section of the state. It provides a technical look at the geological and survey history of the region, specifically noting where the west boundary of the Belen Grant is omitted due to a lack of historical data near the river.
