Rio Grande Del Norte National Monument. 2013-04-23
The Río Grande del Norte National Monument was established on March 25, 2013 by Presidential Proclamation. The monument includes approximately 242,500 acres of public land managed by the Bureau of Land Management. The landscape is comprised of rugged, wide open plains at an average elevation of 7,000 feet, dotted by volcanic cones, and cut by steep canyons with rivers tucked away in their depths. The Río Grande carves an 800 foot deep gorge through layers of volcanic basalt flows and ash. Among the volcanic cones in the Monument, Ute Mountain is the highest, reaching to 10,093 feet.
