2023 Map of Little Grande

About this map

Sierra Grande dominates this corner of Union County, New Mexico, rising above the high plains and defining the local drainage patterns. The terrain transitions from the volcanic slopes of the mountain to the winding watercourses of the South Branch Corrumpa Creek and North Branch Corrumpa Creek. Small ranching settlements like Grande and Little Grande are situated near the highway corridor, while Gallegos and Gallegos Creek mark the southern portion of the sheet. The map reveals a network of local thoroughfares named for area families and landmarks, such as Weatherly Rd, Severo Rd, and Martinez Rd, which provide access to the remote township sections of T28N and T29N. This landscape is a classic example of New Mexico's northeastern ranching country, where seasonal creeks like Seneca Creek provide critical water for the semi-arid environment.
