Tres Rios Field Office - BLM

The Tres Rios Field Office (TRFO) is responsible for the management and stewardship of more than 664,000 acres of public land in southwestern Colorado. TRFO also administers more than 300,000 acres of federal mineral estate underlying private lands (known as split estate) and has trust responsibility for mineral management on 800,000 acres of Tribal lands.

Public lands in the TRFO are incredibly diverse and rich in natural and cultural resources.  From the spectacular Rocky Mountain scenery of the Alpine Triangle to the wealth of Ancestral Puebloan sites in the Four Corners area, Tres Rios lands and resources are truly a national treasure!
