Dunn Butte is a cool mountain peak in the amazing Grand Canyon. It stands tall at 5,714 feet! It's part of a group of three peaks that are connected. These peaks are Angels Gate, Dunn Butte, and Hawkins Butte. Dunn Butte is like a long ridge that sticks out from the main land.

This butte is also close to other famous spots. Wotans Throne is just about one mile away. The popular Cape Royal viewpoint is about two miles from Dunn Butte. The mighty Colorado River flows about two miles north of Dunn Butte, carving out the canyon.

What Dunn Butte is Made Of

Dunn Butte is mostly made of strong rock layers. These layers include the Supai Group and the Redwall Limestone. These rocks are very tough and form the cliffs and flat areas you see. You can find these same rock layers in nearby mountains like Angels Gate and Thor Temple.

The Supai Group is a set of different rock layers. One important layer in this group is the Esplanade Sandstone. This sandstone is very common in the Grand Canyon. It often forms cliffs and flat platforms.

Rocks of Dunn Butte and Nearby Peaks

The bases of Angels Gate, Dunn Butte, and Thor Temple are all made of rocks from the Supai Group. For Thor Temple, the top part is a flat rectangle. It sits on a pyramid shape made of Supai Group rocks. This flat top might have pieces of other eroded rocks, like Hermit Shale.

Angels Gate has two high points made of Coconino Sandstone. These sit on top of the Hermit Shale. Angels Gate and Thor Temple are both very tall, around 6,700 feet high.

Dunn Butte is a bit shorter, at 5,714 feet. Its flat ridgeline is made of the Manakacha Formation. This is another part of the Supai Group. Below it are slopes made of the Watahomigi Formation. All these layers sit on top of the thick Redwall Limestone.
