Most probably this was a wet snow avalanche and they tend to move fairly slowly, say 10 to 40 mph, rather than a fast moving dry snow slide where speeds can be over 80 mph. The photos from the slide at Crosets that stopped on the piste the other day look the same. There’s a potential to do a lot of damage but if you can move they can be avoidable. The most extreme examples occur at high latitudes where permafrost and spring melt combine to create perfect sliding surfaces and slow moving slides occur on slopes as low as 15°.. These are known to take out logging camps and the like.
I can probably see about 50 or 60 of slides like this from the window here currently (in daylight). Some are going full depth and I wonder if the ground is heating up which may create some pockets of danger later.
Crazy warm right now. 10° when I got up and 10° still now. No chance of a refreeze. Very difficult to find good places to go with people.
