Rare lake forms in Death Valley

An oasis teeming with ponds and wildflowers has formed at Death Valley National Park, one of the hottest and driest places in the world, following a major hurricane this summer.

Hurricane Hilary, which hit the area in August, provided some much-needed rainfall for the national park, located in eastern California, according to CNN.

"It is definitely a rare and special event," Death Valley National Park spokesperson Abby Wines told CNN. She added that this kind of precipitation event occurs only about once a decade.

The hurricane arrived in Death Valley on Aug. 19 and continued dousing the desert for 24 hours. Records indicate that 2.2 inches (5.6 centimeters) of rain was measured at Furnace Creek, a site inside the 5,270-square-mile (13,650 square kilometers) national park, breaking the previous record of 1.7 inches (4.3 cm), set in 2022, according to the National Park Service (NPS).

A month after the storm, park officials took a boat onto the ephemeral lake that had formed at Badwater Basin, a salt flat that marks the park's lowest point, and measured its depth at roughly 1 foot (0.3 meters). In the time since, the water has receded to only a few inches.

"I wish we knew exactly how long it will last," Wines told CNN, but she estimated that the pool could hang around until November. If visitors want to see the oasis for themselves, "the sooner, the better," she suggested.

Due to flooding, officials shut down the park temporarily. The park has since reopened, but several roads remain closed, according to the NPS.

"Every road in the park was damaged," Wines told CNN. "We still have a lot of work ahead of us. It was a lot of rain [from Hilary], and it's going to take a while for all that water to evaporate — even in the desert."

The last time a lake sprang up in Death Valley was in 2019, when a 10-mile-long (16 kilometers) body of water formed.
