2013 Map of Grenville

About this map

The high plains of Union County are centered on Grenville, a small settlement defined by its grid of Main St, College St, and Light St. This 2013 survey reveals a landscape where road networks like Sand Mesa Rd and Blind Gap Rd connect isolated outposts and topographical landmarks. To the southwest, the terrain rises toward the distinct heights of Mt Clayton and Horseshoe Mtn, while the Kilburn Hills provide a broken skyline across the southern reaches. This area is etched by seasonal watercourses, including the winding Seneca Cr and Alamos Cr, which cut through the mesa country. The map traces the historical footprint of the region, including the small locality of Marquez and the natural corridor of Cherry Canyon, illustrating the relationship between early ranching-era infrastructure and the volcanic geology of the northeastern New Mexico plateau.
