Plat books vs. recorded plats in Socorro County
Think of the Socorro County plat book as a bound, printed version of ownership: township pages, owner names on each tract, and road maps for places like Abeytas. It's different from a recorded plat, which is the official survey drawing for a subdivision in Magdalena filed with the county.
Search Socorro County parcels by owner, address or ID
There's no separate Socorro County parcel site to hunt for; the NM Office of the State Engineer County Parcels 2025 layer in ArcGIS Map Viewer carries the county's parcels along with the rest of New Mexico. Most people locate their Socorro County tract fastest by searching an address in Magdalena, then clicking the outline. Our Socorro County, NM page keeps the official link and the maps next door to Magdalena in one place.
Finding a printed Socorro County plat book
Whether a current Socorro County edition exists varies, so ask locally in Magdalena before ordering; county offices frequently know if one is in print. An old atlas can help trace when a piece of ground near Abeytas split off from a larger farm.
What a plat book page displays near Magdalena
Many atlases add rural residence listings and road maps, handy on back roads near Escondida. Acreage printed in a county atlas is rough; the deed and a boundary survey decide the real figure for a piece of ground near Abeytas. Genealogists in New Mexico frequently pair an old Socorro County atlas with deed records to follow a farm through the generations.

From Socorro to the back roads
From Socorro, the seat of the county, the map spreads out to Magdalena. Smaller places such as Abeytas, Alamillo, and Alamo appear on the county map as little clusters of lots. Socorro County had an estimated 15,963 people in 2023 (Census Bureau), spread across about 6,646 square miles. Outside Alamillo, most of the county map is farm, ranch or timber ground with large, irregular tracts. Landforms such as the Magdalena Mountains and Bear Mountains shape where roads and homesites fall in the county. With a founding date of 1852, Socorro County has long chains of title on some rural tracts.
