Death Valley Sailing Stones Move With Thin Ice and Light Winds, Scientists Explain

Death Valley Sailing Stones Move With Thin Ice and Light Winds, Scientists Explain

Scientists have solved the mystery of Racetrack Playa’s sailing stones: when the playa floods, shallow water freezes into thin ice sheets (3–5 mm thick). Light winds (3–5 m/s) push these ice panels, which transfer force to rocks over the soft mud, causing them to slide and leave parallel trails. Over about 2.5 months, researchers recorded five movement events—some involving hundreds of stones and distances up to 60+ meters—demonstrating that the rocks move slowly and are driven by rare, gentle wind-ice conditions rather than being lifted by the ice.

Death Valley bursts into a decade’s most dramatic bloom after wet winter

A rare, expansive wildflower bloom has transformed Death Valley National Park after above-average fall and winter rainfall, marking the most extensive bloom in ten years. Blooms are visible at low elevations along Badwater Road with higher-elevation blossoms expected later, and visitors are urged to stay on trails to protect the fragile desert habitat.

"Unveiling the Depth of Death Valley's Ephemeral Lake with SWOT Satellite Imagery"

NASA-led analysis using the U.S.-French SWOT satellite calculated water depths in Death Valley's temporary lake, ranging from about 3 feet to less than 1.5 feet over six weeks, showcasing the satellite's capabilities. The lake, known as Lake Manly, experienced varying water levels and dimensions, with SWOT providing crucial data for understanding unique lake systems. SWOT's KaRIn instrument, a Ka-band radar, is instrumental in measuring water surface levels and providing detailed views of Earth's water bodies, filling data gaps for inland features like lakes and rivers.

"Unprecedented Shifting: Death Valley's Lake Manly Closed to Boating Due to Shallow Waters"

Powerful winds in Death Valley, California, moved a temporary lake known as Lake Manly two miles north over the course of three days, as part of a storm system from the Pacific Northwest. The winds consistently blew between 20 and 33 miles per hour, reaching speeds of 40 to 50 m.p.h. at times, and causing minor damage to trees, power lines, utility poles, and buildings in the area.

"Shrinking Lake Manly in Death Valley: Boating No Longer Allowed"

Death Valley's temporary lake, "Lake Manly," formed by record rains, has now become too shallow and far from the road for boating, closing the opportunity for tourists to kayak or frolic. The lake's formation was an extremely rare event, caused by intense storms and flooding, and its current state is a muddy, wet mess that will eventually dry out into white salt flats. The National Park Service attributes the lake's formation to record amounts of rain and an atmospheric river, making its depth and duration especially uncommon.

"Unprecedented Lake Emerges in Death Valley Amid California Storms"

A temporary lake, named Lake Manly, has formed in Death Valley National Park due to record-breaking rainfall in California, with the basin transforming from a dry landscape to a shallow lake. The lake, which was about 1 foot deep in some areas as of Feb. 14, may last until the end of March, despite initial expectations that it would disappear quickly. The state is still recovering from severe weather that brought record-breaking rainfall and flooding, with all three of California's basins experiencing above-average precipitation levels in February.

"Unexpected Lake Emerges in Death Valley National Park After Heavy Rains"

Record rainstorms in California's Death Valley have replenished Lake Manly, turning the typically dry Badwater Basin into a lake where kayakers are now paddling. The lake, which is currently about six miles long and three miles wide, is a rare sight in one of the driest places on Earth. Park rangers expect the water levels to drop in a matter of weeks, but the lake may last into April or May. Scientists are interested in studying the lake's size and potential uses, while visitors are enjoying the unique opportunity to kayak in Death Valley.

"Rare Lake Emerges in Death Valley National Park: Kayaking Opportunity"

Satellite images show a temporary lake formed in Death Valley's typically dry Badwater Basin after record rains and flooding in eastern California since August. The lake, which has persisted for six months, is a rare sight in one of the hottest, driest, and lowest-elevation places in North America. Visitors are flocking to witness and enjoy this unusual event, with kayaking opportunities available for a limited time. The lake, formed by atmospheric rivers, is expected to last until late March, offering stunning reflections of surrounding peaks in its calm waters.

"Unprecedented California Rainstorms Create and Sustain Lake in Death Valley"

Historic rainstorms in California have created a rare phenomenon at Death Valley, with a lake forming at Badwater Basin after heavy rains and flash floods. The lake, which was initially expected to disappear by October, has been sustained by recent rainstorms and will continue to exist for a longer period. Death Valley, known for its scorching temperatures, has experienced cooler weather this week, with highs in the 50s to 60s. The temporary lake at Badwater Basin is a rare occurrence, as the area was once a former inland lake called Lake Manly, which dried up around 10,000 years ago.
