The Muggins Mountains Wilderness occupies the southwest portion of the range.

The Muggins Mountains Wilderness is in the southwest and borders Dome Valley.

[3] There is flatland, mesas, and hills between the two northern peaks within the Yuma Proving Ground.

The elevation of the mountains is such that there are no standing forests, only desert communities of vegetation.

Desert ironwood, palo verde, catclaw acacia, saguaros, ocotillo, Anderson thornbush, smoketree, and creosote are some locally adapted tree/bush species.
