About this map

The Navajo River and Little Navajo River converge in this high-altitude landscape within the San Juan National Forest near the small settlement of Chromo. The map reveals a complex water management system vital for ranching and agriculture in this arid environment, evidenced by an extensive network of irrigation canals like the Midland Ditch, Enterprise Ditch, and Southside Ditch. These waterways support the livestock operations below the prominent plateaus of Mesa Cortado and Vigil Mesa.

Significant infrastructure for water transport is present, including the Blanco Tunnel and Oso Tunnel, which pierce the mountainous terrain. Oil exploration is also apparent through scattered Oil Wells and drill holes near Confar Hill. This survey captures the region as a working landscape, where traditional irrigation practices and modern energy extraction meet beneath the shadow of Chromo Mountain.
