Nevada Geography

The state is broken up by several north-south mountain ranges. Most of those ranges have inland-draining valleys between them, which belies the image portrayed by the term Great Basin.

Much of the northern part of the state is within the Great Basin Desert, a mild desert that experiences hot temperatures in the summer and sub-freezing temperatures in the winter. Occasionally, moisture from the Arizona Monsoon will cause summer thunderstorms; Pacific storms may blanket the area with snow. The state's highest recorded temperature was 125 °F (52 °C) in Laughlin (elevation of 605 feet (184 m)) on 29 June 1994.[2]

The Humboldt River crosses from east to west across the northern part of the state, draining into the Humboldt Sink near Lovelock. Several rivers drain from the Sierra Nevada eastward, including the Walker, Truckee and Carson rivers.

The mountain ranges, some of which have peaks above 13,000 feet (4,000 m), harbor lush forests high above desert plains, creating sky islands for endemic species. The valleys are often no lower in elevation than 3,000 feet (900 m).

The eastern parts of the state receive more summer moisture and have a slightly more verdant terrain. Sagebrush grows everywhere and some rivers and streams break the desert terrain.

The southern third of the state, including the Las Vegas area, is within the Mojave Desert. The area receives less precipitation in the winter, but is closer to the Arizona Monsoon in the summer. The terrain is also lower, mostly below 4,000 feet (1,200 m), creating conditions for hotter summer days and colder winter nights due to inversion.

Nevada and California have by far the longest diagonal line (in respect to the cardinal directions) as a state boundary at just over 400 miles (640 km). (There are a very few, much smaller diagonal boundaries in the northeastern states and Washington, D.C., with the longer exceptions not being at such a steep angle.) All other state boundaries, but one, are lines of latitude, longitude, or are irregular and based on rivers, mountains, lakes, etc. (A circular border exists between Delaware and Pennsylvania.) This line begins in Lake Tahoe nearly 4 miles (6 km) offshore (in the direction of the boundary), and continues to the Colorado River where the Nevada, California, and Arizona boundaries merge 12 miles (19 km) southwest of the Laughlin Bridge.

The largest mountain range in the southern portion of the state is the Spring Mountains, just west of Las Vegas. The state's lowest point is along the Colorado River, south of Laughlin.

Some have suggested that Nevada annex the town of Wendover, Utah, which would be merged with West Wendover, Nevada. This deal will require the permission of both the Nevada and Utah legislatures and the U.S. Congress.
