Sierra Ancha Wilderness, Wilderness area in Tonto National Forest, Arizona, United States

Sierra Ancha Wilderness is a protected area within Tonto National Forest featuring deep canyons, steep cliff faces, and thick pine forests. The landscape varies significantly in elevation and includes several creeks and natural water features that sustain the ecosystem.

The wilderness was designated as a protected Primitive Area in 1933 to preserve its natural character. The site contains evidence of indigenous habitation through stone structures and cliff dwellings built using traditional materials.

Archaeologists call the cliff-dwelling builders of these canyons the "Anchan Tradition." Tree-ring dating of construction timbers shows the ruins were built and occupied from 1280 to 1350, a span of about seventy years. Their tools and pottery show strong Mogollon influence, though the Sierra Anchas sat near the center of the Salado region.

The wilderness offers a network of trails suitable for day hikes and overnight trips with backcountry camping options. Plan ahead and bring your own water supply, as natural sources can be unpredictable or distant from main routes.

The wilderness contains Devil's Chasm ruins, an archaeological site that remains largely unknown to most visitors. Colcord Falls provides a natural swimming hole when water flow is sufficient, offering an unexpected cool respite in this remote terrain.
