It’s been a big year for snow in the Sierra Nevada range. This is the time of year—April 1—when the snowpack is typically at its peak and on Tuesday, when surveyors do their monthly manual survey, they’re likely to find a snowpack at about 160 percent of the average. Mammoth Mountain, which soars to 11,000 feet in the central Sierra, has had 50 feet of snow pile onto its sweeping inclines. The nearby Mammoth ski resort tweeted that it had broken its snowfall record for February—and it was only two weeks into the month.
