But not every part of the US suffered. Although official totals are not yet available the country's north western states like Washington and Wyoming had consistent heavy snowfall all season and resorts like Jackson Hole say they are very pleased with winter 2011-12 for both snow and business.

Crystal Mountain expects to be open late in to spring and possibly even early summer and Mt Baker still has more than 7m (23+ feet) lying on its slopes having been the world's snowiest resort for most of 2012.

Similarly and more unusually southern states like New Mexico received heavy snowfall in mid-winter when the main ski states like California and Colorado to the north were comparatively warm and dry.

Both northern and southern states say their business could in fact have been better if the general perception of "no snow" coming from the main ski states and general unseasonal warmth across most of the US mainland had not made people think they were in the same boat.

Some commentators are saying that Colorado's winter was the driest for around 40 years, since the 1970s, but again official data is yet to appear. What numbers there are indicate that numbers were down by around 7% but that in some destination resorts business went up, despite the lack of much snow until February, as people had booked ahead and destination skiers were less influenced by snow conditions and happy to do other things.

It's not clear also if there'll be any knock on effect for winter 12-13 bookings but resorts like Vail are already aggressively marketing special early booking deals on lift tickets and to the international market, accommodation packages. Then again they would be by now anyway.

California had a particularly strained early season after most resorts in the state set snowfall records last winter and nine were open for July 4th. Here there was little snow either until early March but subsequent (and still on-going) heavy snowfalls allowed for a late recovery and again several resorts including Alpine Meadows and Mammoth Mountain have extended their season s in to May.

In summer and autumn 2011 these resorts had been talking up a return of the 'La Nina' weather pattern of cooler air from the Pacific which they hoped then would again bring them season-long heavy snowfall as in 2010-11 and as did happen to the north and south of them.

Meteorologists are now saying that La Nina was in fact the reason why it was unseasonably warm through much of winter 2011-12, however some season-ending press release summaries from Californian resorts are saying that they expect a snowy winter 2012-13 thanks to meteorologists predicting a third successive year of La Nina.
