Mohave County contains parts of the Grand Canyon National Park and Lake Mead National Recreation Area and all of the Grand Canyon-Parashant National Monument. The Kaibab, Fort Mojave and Hualapai Indian Reservations also lie within the county.
Mohave County contains approximately 13,400 square miles of land. It has no less than 148 canyons within its boundaries, most of which help make up a large portion of the Grand Canyon of the Colorado River that separates the top 1/3 of Mohave County from the bottom 2/3. The county is bordered by three rivers and one creek along with four lakes that are impounded behind dams on the Colorado and Bill Williams Rivers.
The county is intersected by 21 mountain ranges and the corresponding valleys in between. There are five climate zones in Arizona and Mohave County is the only county in the state that contains all five.
Most of Mohave County is located where the Sonoran and Mohave Deserts meet. It varies in elevation from 500 to 8,000 feet, but it is mostly desert terrain and high chaparral with hot summer day temperatures one can expect from a desert and cool summer nights. In winter, daytime temperatures are moderate to cool, with cold nights and occasional rain or snow in the higher elevations.
