San Juan National Forest defines the eastern expanse of this 1984 survey, where the rugged terrain of Archuleta County is marked by a complex network of canyons and water management features. The Little Blanco Highline Ditch and various other irrigation channels like the Ditch winding through Echo Canyon illustrate the critical role of water diversion in this high-altitude landscape. Evidence of earlier infrastructure remains visible in the Old Railroad Grade that cuts across the western slopes near Turkey Mountain. Recreational and industrial markers are scattered throughout the territory, from the Echo Canyon Reservoir State Fishing Area in the northwest to the Gaging Sta along the Rito Blanco. Prominent peaks like Serviceberry Mountain and the broad Eightmile Mesa provide significant navigational landmarks for those tracing the historical geography of this section of the Colorado-New Mexico border region.
