The lowest point in the United States of America is Badwater Basin in Death Valley, California, at 282 feet (86 meters) below sea level.
This exact elevation makes Badwater Basin not only the lowest point in the United States but also the lowest point in all of North America. The basin lies within Death Valley National Park in Inyo County, approximately 140 miles southeast of Las Vegas and 84.6 miles east-southeast of Mount Whitney, the highest point in the contiguous United States.
Key Facts About Badwater Basin
The salt flat expanse of Badwater Basin covers nearly 200 square miles (518 square kilometers) and consists primarily of sodium chloride (table salt), along with calcite, gypsum, and borax. Visitors can walk across the distinctive white crust, though park officials warn that the salt flats can be hazardous as the crust may be thin over deep mud in many areas.
- Elevation: 282 feet (86 meters) below sea level
- Location: Death Valley National Park, Inyo County, California
- Coordinates: 36°14′23″N 116°50′5″W (36.23972°N, 116.83472°W)
- Continent: Lowest point in North America
- Park designation: Official National Park Service landmark
- Monthly average rainfall: Less than 2 inches annually
- Record high temperature: 134°F (56.7°C) recorded July 10, 1913
The geological formation of Badwater Basin resulted from tectonic activity that created the Death Valley graben, a down-dropped block of Earth's crust bounded by fault lines. This structural depression has been collecting water and sediment for millions of years, creating the vast salt flats visible today.
Historical Context and Discovery
The first recorded survey of Badwater Basin's elevation occurred during the US Geological Survey's systematic mapping of Death Valley in the late 19th century. The 282-foot below-sea-level measurement has been verified multiple times using modern GPS technology, confirming its status as America's absolute low point.

- 1890s: US Geological Survey begins systematic elevation measurements of Death Valley region
- 1933: Death Valley National Monument established, protecting Badwater Basin
- 1994: Death Valley National Monument redesignated as Death Valley National Park

Death Valley holds the world temperature record for highest air temperature ever reliably measured on Earth: 134°F (56.7°C) at Greenland Ranch (now Furnace Creek) on July 10, 1913. The valley's lowest temperature was 15°F (-9°C), recorded at Greenland Ranch on January 2, 1913.
Comparison with Other Low Points
Understanding Badwater Basin's significance requires comparing it to other notable low points globally and across the United States. The Dead Sea shoreline remains the world's lowest exposed point at 1,391 feet (424 meters) below sea level, making it significantly lower than Badwater Basin.
| Location | Elevation (feet) | Elevation (meters) | Continent |
|---|---|---|---|
| Badwater Basin, California, USA | -282 | -86 | North America |
| Dead Sea (shoreline), Israel/Jordan | -1,391 | -424 | Asia |
| Laguna del Carbón, Argentina | -344 | -105 | South America |
| Chicago, Illinois, USA | 579 | 176 | North America |
| Delaware (state average), USA | 60 | 20 | North America |
Interestingly, Laguna del Carbón in Argentina has an elevation of -105 meters (-344 feet), making it the lowest point in the Western Hemisphere, though Badwater Basin is often mistakenly described with this title. The confusion arises because Laguna del Carbón is less well-known and harder to access than the popular tourist destination of Badwater Basin.
Visiting Badwater Basin Today
The parking area and boardwalk at Badwater Basin provide safe access to the salt flats for thousands of visitors annually. A sign marking the low point stands at a small pool rather than at the actual lowest point, which varies slightly depending on rainfall and evaporation patterns.
Geological and Climate Significance
The endorheic basin nature of Badwater Basin means it has no outlet to the ocean. Water flowing into the basin from surrounding mountains evaporates, leaving behind dissolved minerals that accumulate over time. This process has created the thick salt deposits visible today.
Death Valley receives less than 2 inches of precipitation annually on average, making it the driest place in North America. The combination of extreme heat, minimal rainfall, and below-sea-level elevation creates unique geological and ecological conditions found nowhere else on the continent.

The extreme elevation contrast within Death Valley National Park is remarkable: less than 20 miles west of Badwater Basin rises Telescope Peak at 11,049 feet (3,368 meters), creating a vertical relief of nearly 11,331 feet within a short distance.
Scientific Monitoring and Research
Scientists continue to monitor elevation changes at Badwater Basin using advanced GPS equipment and satellite imagery. While the 282-foot measurement remains stable for practical purposes, the actual lowest point shifts slightly based on rainfall, evaporation, and sediment deposition patterns.
Research at Badwater Basin contributes to understanding drought patterns, climate change impacts on desert ecosystems, and the geological processes that create and maintain endorheic basins. The site serves as a natural laboratory for studying extreme environmental conditions.
| Measurement Type | Value | Unit | Last Verified |
|---|---|---|---|
| Elevation | -282 | feet | 2004 (GPS) |
| Elevation | -86 | meters | 2004 (GPS) |
| Annual rainfall | 1.94 | inches | 2025 average |
| Basin area | 200 | square miles | 2023 survey |
| Salt composition | 95% | sodium chloride | 2022 analysis |
The tourist infrastructure around Badwater Basin includes interpretive signs, boardwalks, and parking facilities that allow visitors to safely experience this geological wonder while protecting the fragile salt crust ecosystem.
Why Badwater Basin's Title Remains Secure
Badwater Basin isn't in jeopardy of losing its title as the lowest point in the United States anytime soon, as geological processes that created the basin operate over millions of years rather than decades. The tectonic forces continuing to pull the valley floor downward actually maintain and slightly increase the elevation differential.
For travelers, researchers, and geography enthusiasts, Badwater Basin represents America's absolute low point-a unique natural landmark that combines extreme elevation, dramatic landscape, and scientific significance in one unforgettable location.
Key concerns and solutions for What Is The Lowest Point In The United States Of America
How do I get to Badwater Basin?
From the Furnace Creek Visitor Center, head south on CA-190E for 1.3 miles, then turn right onto Badwater Road. Drive 16.5 miles to the parking area on the right. From Death Valley Junction, take CA-190 West for 28.9 miles to Badwater Road, turn left, and drive 16.5 miles to the parking area.
Is it safe to walk on the salt flats?
The salt flats are hazardous to traverse in many areas because the white crust is often only a thin layer over deep mud. Visitors should stay on designated paths and avoid walking far from the boardwalk without proper preparation and knowledge of current conditions.
What is the best time to visit?
Winter months (November through March) offer the most comfortable temperatures for visiting Badwater Basin. Summer temperatures regularly exceed 120°F (49°C), making outdoor activity dangerous without extreme precautions.
Why is it called Badwater?
The name "Badwater" comes from the pool's highly mineralized water, which is undrinkable due to its salt content. The pool contains concentrated brine rather than fresh water, making it useless for drinking or irrigation.
Can you swim in Badwater Basin?
No, swimming is not possible. The "pool" at Badwater is a small, shallow pool of highly mineralized brine, not a swimming body of water. The water is undrinkable and unsafe for recreational swimming due to its extreme salt concentration.
What is the nearest town to Badwater Basin?
Furnace Creek, located approximately 18 miles north of Badwater Basin, serves as the main visitor hub for Death Valley National Park. It offers lodging, dining, fuel, and the Furnace Creek Visitor Center.
Is Badwater Basin visible from space?
While the vast white salt flats of Badwater Basin are visible from aircraft at high altitude, they are not distinctly visible from space with the naked eye due to their relatively small size compared to Earth's surface.
