Mount Trumbull Wilderness

Mount Trumbull Wilderness is a protected area on the Uinkaret Plateau covering roughly 7,880 acres of forest. The slopes support a mix of pinyon pine, juniper, and ponderosa pine trees that create dense woodland throughout the region.

Ancestral Puebloan peoples established settlements in this area centuries ago, leaving behind structures and artifacts. In the 1800s, Mormon settlers arrived and harvested timber from portions of the forest for building and trade.

Native American communities built settlements throughout this area, leaving behind structures and sites visible to those who explore carefully. Walking through the forest, visitors encounter these remnants and understand how people lived here before modern times.

The area is reached via Mount Trumbull Road, which branches off from Arizona Highway 389 and leads to the main entrance. Nixon Spring Campground nearby offers a base for camping if you plan to spend the night.

The land rests on a basalt lava flow that erupted roughly 3.6 million years ago, representing one of the first volcanic events in the Uinkaret volcanic field. This ancient volcanic ground shapes the terrain and soil composition visible throughout the area.
