Mammoth Mountain digs out after heavy snow stormThis winter has been a boon for ski resorts across California, and the yards of snow that have fallen over the Sierra Nevada will last well into the summer. AccuWeather Senior Meteorologist and longtime California resident Ken Clark said that Mammoth Mountain would likely remain open to skiers well into June and maybe even Independence Day. This winter has been the snowiest at the resort since 2016-17, when 617.5 inches of snow fell -- the second snowiest in Mammoth Mountain history. The mountain remained open until Aug. 6, 2017, due to the plethora of snow that covered the mountain, according to Snowpak.com. Since 1969, the mountain has only measured over 600 inches of snow during two winter seasons, with the snowiest being the winter of 2010-11, when 668.5 inches accumulated.
