Working inside a nearly 18-foot-deep snow pit at the UC Berkeley Central Sierra Snow Lab, from left, Shaun Joseph, Claudia Norman, Helena Middleton take measurements of snow temperatures ahead of a weather storm on March 9, 2023, in Soda Springs, Calif. A new study finds the snow deluge in California, which quickly erased a two decade long megadrought, was essentially a once-in-a-lifetime rescue from above. The study authors coined the term “snow deluge” for one-in-20-year heavy snowfalls. (Karl Mondon/Bay Area News Group via AP, File)
