Mount Trumbull Wilderness, Protected wilderness area in Mohave County, Arizona.

Mount Trumbull Wilderness covers 7,880 acres on the Uinkaret Plateau, with Mount Trumbull rising to 8,028 feet. A broad ridge slopes gently upward to the summit, covered in dense dark green vegetation with patches of tan and gray ground. Below the crest, the slope descends into lower forested terrain, and a taller evergreen stands in the foreground.

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.

The name Parashant comes from a Paiute phrase meaning "tanned deer hide", hinting the plateau once supported large herds. Ancestral Puebloans left scattered buildings, petroglyphs, grinding stones and arrowheads across the area, and an archaeological field school works here each summer.

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 mesa's cap is a 3.6-million-year-old dark grey basalt flow, among the first eruptions of the Uinkaret volcanic field. A later, undated cinder cone on top ejected bright red cinders and lava bombs, which can be seen along the switchback trail. The hard cap also shields the colourful Moenkopi Formation beneath from erosion.
