The Colorado River forms the county's southeastern boundary, with Hoover Dam forming Lake Mead along much of its length. The lowest point in the state of Nevada is located on the Colorado River just south of Laughlin in Clark County, where it flows out of Nevada into California and Arizona. Las Vegas is a valley. By definition, Greater Las Vegas is a tectonic valley, surrounded by four mountain ranges, with nearby Mount Charleston being the highest elevation at 11,918 ft (3,633 m), located to the northwest. Other than the forests on Mount Charleston, the geography in Clark County is a desert. Creosote bushes are the main native vegetation, and the mountains are mostly rocky with little vegetation.

Environmental factors

Clark County contains a diverse desert flora and fauna, including higher elevation mountain areas, the desert floor and the Colorado River/Lake Mead ecosystems. Variations in diurnal temperature as well as seasonal swings in temperature create demanding adaptation elements on the species of this county. Additional pressure has been placed on species survival by the rapid human population expansion, especially since 1970.

Correspondingly air quality levels prior to the 1960s were in a favorable range, but the proliferation of automobiles with the human population expansion created circumstances where some Federal Air Quality Standards began to be violated in the 1980s.

To plan for the wave of development forecast by 1980, Clark County embarked on a regional Environmental Impact Assessment funded by a Federal Section 208 program, with Sedway Cooke conducting the planning work and Earth Metrics performing environmental analysis. This endeavor projected future population growth, land use changes and environmental impacts.

To prevent the loss of federal funds due to unacceptable dust levels in the Las Vegas valley, in 2003 the Nevada Air Quality Management division (under direction of Clark County officials) created the massive "Don't Be a Dusthole" campaign. The campaign successfully raised awareness of dust pollution in the Las Vegas valley, quantifiably reducing pollutants and preserving ongoing federal funding.

Located in Apex is the Apex Landfill which at 2,200 acres (890 ha) is the largest landfill in the United States. Republic Services owns and operates the landfill.

Earthquake hazards

Nevada is the third most seismically active state in the U.S. (after Alaska and California); it has been estimated by the United States Geological Survey (USGS) that over the next 50 years Clark County has a 10–20% chance of a M6.0 or greater earthquake occurring within 50 km of Las Vegas.
