In this photo provided by Mammoth Mountain Ski Area, snow falls on Mammoth Mountain Monday, Oct. 18, 2021, in Mammoth Lakes, Calif. A cold front passing through drought-stricken California has brought snow to the northern Sierra Nevada and rain, showers or drizzle elsewhere. The National Weather Service says the Sierra snowfall Sunday night was significant enough to impact travel over the higher passes. (Peter Morning/MMSA via AP)
