Along the western side of the recreation area, discover the Nellis Wash Wilderness area nestled in the isolated Newberry Mountains. Fingerlike drainages and alluvial fans extend eastward from the mountains toward Lake Mohave. Some mining has occurred in the area and adds an historic element that is a remnant of the old west. Summer temperatures can reach 120 degrees Fahrenheit and the lack of water can be cause for caution when hiking or camping in the area. Jackrabbits, side-blotched lizards, snakes, and desert tortoise make their home in the area.
