History of Clark County
Las Vegas, the biggest city in Nevada, has been the main city of Clark County since the county was created. The county was officially formed on February 5, 1909. It was made from a part of Lincoln County. It started operating on July 1, 1909.
Early Inhabitants and Trails
Native Americans lived in the Las Vegas Valley over 10,000 years ago. The Paiute people moved into the area around 700 AD. Later, American fur trappers explored these lands. Their stories led to the first trade route from New Mexico to California in 1829. This route followed the Virgin and Colorado Rivers. It was part of the Old Spanish Trail.
Over time, this trail was changed to be more direct. It moved north from the Colorado River to areas with water, like Las Vegas. In 1844, explorer John C. Frémont added his own shortcut to the trail.
Becoming Part of the United States
What is now Clark County became part of the United States after the Mexican–American War. It was first part of the New Mexico Territory. In 1847, members of the Mormon Battalion created a wagon route through the county. This became known as the "Southern Route" of the California Trail. It was a popular winter route for people going to California during the California Gold Rush.
By the mid-1850s, this route was used for trade between Salt Lake City and Los Angeles. Mormons also built a fort in Las Vegas in the mid-1850s. In the 1860s, more Mormon settlements were started along the Virgin and Muddy Rivers.
County Formation and Naming
Before Nevada became a state, this area was part of Mohave County, Arizona Territory, in 1863. In 1865, it became part of Pah-Ute County, Arizona Territory. In 1866, the part of Pah-Ute County north and west of the Colorado River was given to the new state of Nevada. Arizona fought this change until 1871. Pah-Ute County then became part of Lincoln County.
Clark County was named after William A. Clark. He was a very rich copper businessman and a U.S. Senator from Montana. He helped build the San Pedro, Los Angeles and Salt Lake Railroad through the area. This railroad was very important for the region's early growth.
Today, Clark County is a huge tourist spot. It has about 150,000 hotel rooms! The famous Las Vegas Strip is not actually inside the city limits of Las Vegas. It's in an area called Paradise, which is not an official city. However, it is still part of the larger Las Vegas Valley.
Environmental Challenges
Over time, droughts have become more common and severe in Southern Nevada. This is partly due to climate change. These droughts put a lot of stress on the water supply for Clark County and Las Vegas.
Geography of Clark County
The Colorado River forms the southeastern border of Clark County. The Hoover Dam creates Lake Mead along much of this river. The lowest point in Nevada is in Clark County, south of Laughlin. This is where the Colorado River flows out of Nevada into California and Arizona.
Greater Las Vegas is a valley surrounded by four mountain ranges. Mount Charleston is the highest point, reaching 11,918 feet. It is located to the northwest. Most of Clark County is a desert, except for the forests on Mount Charleston. The main plants are creosote bushes. The mountains are mostly rocky with very little plant life. The land generally slopes towards the south and east.
The county covers about 8,061 square miles. About 7,891 square miles are land, and 170 square miles are water.
Neighboring Counties
Clark County shares borders with several other counties:
- Lincoln County – to the north
- Mohave County, Arizona – to the east (this county uses Mountain Time)
- San Bernardino County, California – to the south
- Inyo County, California – to the northwest
- Nye County – to the west
Protected Natural Areas

Clark County has many protected natural areas. These areas help preserve the unique desert environment. Some of these include:
- Avi Kwa Ame National Monument
- Desert National Wildlife Refuge (part of it)
- Humboldt-Toiyabe National Forest (part of it)
- Lake Mead National Recreation Area (part of it)
- Moapa Valley National Wildlife Refuge
- Red Rock Canyon National Conservation Area
- Sloan Canyon National Conservation Area
- Spring Mountains National Recreation Area (part of it)
- Tule Springs Fossil Beds National Monument (part of it)
There are also twenty official wilderness areas in Clark County. These are special places where the land is kept wild and untouched. Many of them are managed by the Bureau of Land Management (BLM).
Environmental Factors
Clark County has a wide variety of desert plants and animals. This includes life in the mountains, on the desert floor, and around the Colorado River and Lake Mead. The big changes in daily and seasonal temperatures make it challenging for species to live here.
Since 1970, the human population has grown a lot. This growth has put more pressure on the local wildlife. Also, the air quality was good before the 1960s. But with more cars and people, some air quality standards were not met starting in the 1980s.
To help with dust pollution, Clark County started the "Don't Be a Dusthole" campaign in 2003. This campaign successfully made people more aware of dust. It helped reduce pollution and kept federal funding for the area.
The Apex Landfill in Clark County is the largest landfill in the United States. It covers 2,200 acres.
Earthquake Risks
Nevada is the third most active state for earthquakes in the U.S. (after Alaska and California). Experts believe there is a 10–20% chance that Clark County could have a strong earthquake (M6.0 or greater) within 50 kilometers of Las Vegas in the next 50 years.
