LAS VEGAS — 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.
A UNLV study published in the Geological Society of America found that the exposed rock, which hasn’t been visible since the 1930s, contains ash from volcanoes in Wyoming, California and Idaho from 12 million to 32,000 years ago.
