Trinidad serves as the focal point of this Southern Colorado landscape, situated where the Purgatoire River flows through the Picketwire Valley. The western edge of the city is defined by the significant waters of Trinidad Lake, created by the Trinidad Dam. This 2010 survey highlights a region deeply defined by its industrial roots, specifically the extensive coal mining operations that once drove the local economy. A dense network of mines, including the Starkville Mine, Main Cokedale Mine, and Animas Mine, are scattered across the surrounding canyons and mesas.
