Industrial infrastructure and steep-walled canyons define the landscape of the Maxwell Grant in the early 1950s. Along the Purgatoire River, also labeled as the Picketwire River, the coal-driven economy of the region is evident through the extensive workings of the Frederick Mine. This operation includes a Pipe Drain, an Airshaft, and a Frederick Mine Shaft noted as inactive by the time of this field check. Nearby, the settlement of Segundo is distinguished by its Coke Ovens, while the Colorado and Wyoming railroad tracks follow the river valley to serve the local mines.
