Mammoth Mountain picked up 29cm overnight. Alta and Snowbird in Utah added 26cm each, with incoming snow flagged at all three resorts.
Mammoth Mountain topped the list, registering 29cm of fresh snow overnight. The Sierra resort saw the largest single total among qualifying lifts, with the new return concentrated at higher elevations and across named powder fields. Resort feeds show "Incoming Snow", so the fresh deposit is still in play for the first lifts. This is the standout figure for the day, and it matters because Mammoth often sets the early-season tone for the Sierra.
Utah supplied the rest of the movers. Alta and Snowbird each recorded 26cm, both flagged as "Incoming Snow" as well. That puts the Wasatch on a similar footing to the Sierra for this cycle, with the heavy end of accumulation sitting on wind-loaded ridges and steep north aspects. Only three resorts qualified in today’s update, so coverage is concentrated rather than widespread. The pattern favoured high terrain, so lower slopes and valley approaches will show less change than summit cams suggest. For skiers and riders chasing fresh turns, Mammoth, Alta and Snowbird are the clear targets; other resorts through the region reported either trace amounts or no qualifying totals for this bulletin.
The common "Incoming Snow" status across the three resorts suggests the event is ongoing, not finished. That means conditions are likely to continue freshening at elevation over the next day or two, with the best gains on upper faces and in zones sheltered from solar exposure. Expect the new snow to sit on top of existing bases rather than radically rebuilding them, so line selection and wind-awareness will matter. Check local lift and road reports before travelling, and plan for variable coverage below the tree line.
