2022 Map of Chromo

About this map

The San Juan National Forest defines the northern reaches of this map, where the high terrain gives way to a complex network of irrigation and water management in the Chromo area. The landscape is characterized by prominent flat-topped mesas such as Mesa Cortado, Vigil Mesa, and Abeyta Mesa, while drainage is dominated by the Navajo River and Little Navajo River. A sophisticated system of human-made water diversions is visible, including the Blanco Tunnel, Oso Tunnel, and numerous named ditches like the Midland Ditch and Enterprise Ditch. These features reflect a legacy of ranching and water rights in southern Archuleta County, where the desert-edge geography required extensive engineering to sustain agriculture. Historic trails such as the Blue Creek Winter Trl and Navajo Peak Trl provide a look at the traditional routes used to navigate these peaks and canyons before modern development.
