2020 Map of Boiler Gap

About this map

Boiler Gap and Sand Gap define the high terrain of Union County, marking natural passages through the plateaus of northeastern New Mexico. This landscape is shaped by the drainage patterns of seasonal watercourses like Corrumpa Cr and Rafael Cr to the north, and Alamosita Cr to the south. The area is characterized by a sparse network of county roads, including Royce Rd and Elam Rd, which follow the township and range lines established by the Public Land Survey System. The map documents a predominantly open ranching or grazing landscape where topographical features like Sand Cr serve as the primary landmarks in an area with few permanent settlements.
