The Purgatoire River carves a deep valley through the high plains of southern Colorado, anchoring a landscape shaped by coal mining and transport. In the shadow of Pio Hill, the city of Trinidad serves as the regional hub, flanked by the industrial outposts of Engleville and El Moro. The terrain south of the river is dense with mining history, featuring the Highline Mine and Engleville Mine, while the canyon-cut highlands are marked by features like Number Six Canyon and Eagle Rock.
