Mammoth Mountain ski area in California says its ski season will last until the end of Sunday, August 6th this year, the second time in its history that it has made its season stretch in to August.

In total staying open to August 6th will mean it has been operating for 270 days since its season started nine months earlier at the start of November last year.

It’s one of Mammoth’s longest ever seasons but it has managed longer in the past, staying open for 300 days to August 14th back in the 1994-95 season 22 years ago.

Mammoth still has a 90cm snow base and ten trails open served by three lifts.  That’s about 10% of the snow depth it posted through last winter which was the deepest in the world for a major ski area by several metres and more than treble what most areas reached.

In total it received 618 inches (15.7 metres) of snowfall last season although that was not quite the snowiest winter ever, despite January 2017 being the snowiest ever month.  That record is still held by winter 2010-2011 when 668 inches fell.

Mammoth’s decision to set a closing date follows that of fellow Californian resort Squaw Valley to the north which had initially said it had hoped to stay open on Saturdays through 2017 indefinitely, and potentially through to the start of the 2017-18 winter season, but found unseasonably warm summer temperatures (Following the exceptionally snowy winter) led to a rapid thaw it ended its season 10 days ago.

Since their long spring and summer 2017 ski seasons began both Mammoth and Squaw Valley have been bought by the same new multi-ski resort owning company, co-run by Aspen in Colorado.

Copper Mountain in Colorado which has a summer terrain park open also plans to end its summer snow season at the start of August and Whistler Blackcomb up in BC, Canada has finished its 2017 summer glacier season and thus from August 7th only one ski area will be open in North America – the Timberline ski field on Mt Hood in Oregon.  This is a permanent snow field that’s traditionally open 10-11 months of the year, closing only in September.

Three lifts serve the runs here which include two terrain parks and pipes that are open from 7am to 2pm daily in summer.
