2010 Map of Grenville

About this map

Grenville and the nearby settlement of Marquez anchor this high-plains landscape in Union County, New Mexico. The geography is defined by volcanic features and distinct drainage patterns, including the prominent peaks of Mount Clayton and Horseshoe Mountain which rise above the surrounding Kilburn Hills. The local economy and land use are reflected in the presence of the Seneca Pit mine and an extensive network of rural routes such as County Hwy A-059. Arid watercourses like Seneca Creek and Alamos Creek carve through the terrain, while Sand Mesa and Cherry Canyon provide further topographical variation to this sparsely populated cattle-country region during the early twenty-first century.
