About this map

Egeria Park serves as a central drainage basin in this 1970s landscape, where the Denver and Rio Grande Western railroad corridor follows the narrow valley of Chimney Creek. The map documents a highly managed water system essential for high-altitude ranching and conservation, featuring numerous upland catchments such as Sterner Reservoir, Crossan Reservoir, and the Egeria Creek Reservoir.

The rugged terrain transitions from the timbered heights of the Routt National Forest and White River National Forest down toward the settlement of Trapper. Notable specialized landmarks include the Finger Rock Fish Hatchery along Finger Rock Fish Hatchery creek and several named highland clearings like Moody Park and Moore Park. The network of irrigation infrastructure is further detailed through features like the Roaring Fork Ditch and Five Pine Mesa Ditch, tracing the complex movement of water across Porcupine Ridge.
