Frederick Mine and its associated industrial infrastructure anchor the northern edge of this Las Animas County landscape, reflecting the coal mining activity along the Picketwire River valley. The settlements of Segundo, Valdez, and Tijeras cluster near the Colorado and Wyoming River railroad line, where historical operations like the Coke Oven and various Frederick Mine Shafts (Inactive) indicate a shifting economy at the time of the 1951 field check.
