About the Rio Grande del Norte National Monument
Río Grande del Norte National Monument was established on March 25, 2013 by Presidential Proclamation. The new monument includes approximately 242,500 acres comprised of rugged, wide open plains, volcanic cones, and steep canyons with rivers tucked away in their depths. The Rio Grande carves an 800 foot deep gorge through high plains at an elevation of about 7,000 feet. Among the volcanic cones dotting the plains, Ute Mountain is the highest, reaching to 10,093 feet. Lying between the San Juan Mountains and Sangre de Cristo Mountains, this area is also an important area for wintering animals, and provides a corridor by which wildlife move between the two mountain ranges.
