Mammoth gets lots of snow all winter. The ski season, one of the longest in North America, is open until the end of May 2016. Sometimes it even lasts until July 4. El Nino has made sure that the Sierra Nevada Mountain ski area continues to have a steady amount of snow. The resort is famous for its spring skiing events. Many youngsters go there to celebrate Spring Break. Slope-side barbecues and the traditional Pond Skim, when people use their skis and snowboards to straight-line across a 110-foot pond, are huge attractions. Mammoth is a preferred family destination for spring skiing because of its 3,500 acres of skiable terrain. There is a trail for skiers of all skillsets.
