Boats and bodies aren’t the only things revealing secrets at Lake Mead. Newly-exposed rock at Lake Mead has revealed that the Las Vegas Valley could be impacted by volcanic ash from neighboring states.

When millions of grasshoppers swarmed the Las Vegas valley a few years ago, tourist and locals alike were taken by surprise. During 2019’s infestation, Channel 13 talked with people who couldn’t stand the sight of the creatures or the crunch sound of dead grasshoppers being walked on.

Not only have Lake Mead’s dwindling water levels exposed human remains and old relics but now decades-old sedimentary rocks containing volcanic ash are being seen at the lake, according to a recent UNLV study.

New observations are challenging a hypothesis about what produces these energetic bursts of radio waves.

As the climate crisis continues to affect the American West, sunken boats and human remains aren’t the only surprises to be revealed by record-low water levels at Lake Mead. Sedimentary rocks that hadn’t been seen since the 1930s are now exposed along the constantly changing shoreline, and a UNLV study of the deposits has discovered that many of these rocks also contain ash from volcanoes as far away as Idaho, Wyoming, and California that rained down on Southern Nevada as many as 12 million years ago.

Lake Mead's receding water levels are now revealing ancient volcanic eruptions from millions of years ago.

A peculiar repeating fast radio burst seems to be coming from a dynamic environment in an otherwise uninteresting region, leaving researchers scratching their heads as to the burst’s origin.

Mysterious fast radio bursts release as much energy as the Sun pours out in a year - and newly published research has deepened the mystery around them.

A diamond contains the only known sample of a mineral from Earth’s mantle—and hints at oceans’ worth of water hidden deep within our planet

The mineral may shake things up by changing its identity at high pressure and temperature

A beautiful blue flaw in a gem-quality diamond from Botswana is actually a tiny fragment of Earth’s deep interior—and it suggests our planet’s mantle contains oceans’ worth of water.
