The Eagle County town of Basalt, shown here around 1900, lies about a dozen miles northwest of Aspen at the junction of Fryingpan and Roaring Fork Rivers. The beehive-shaped structures in the foreground are ovens used to produce coke, a coal-based fuel that burns hotter and was sent to silver smelters in Aspen. The Roaring Fork River is seen at left, and the Fryingpan River flows through the foreground behind the coke ovens. A freight train rolls along tracks at center and houses are clustered on the hillside to the right.
