Wind transport, terrain features and buried toboggans. Last week we had strong winds 85-145 KPH with 60 centimetres of snow. The distribution of the snow depends on a lot of factors. Wind speed, terrain features, slope angles, crystal size, and fetches. Snow scientists like Lacossa & Barber,2010 describe : "Snow transported by the wind tends to be deposited preferentially in the lee of topographic disturbances such as ridges and erode preferentially from flat areas where an adequate fetch to establish wind exists". Its amazing that 60 centimetres of snow and strong variable winds can bury these toboggans 3.75 meters deep. They are normally placed on end with the handles extended up leaning against the rock.

It was a lot of work to get both of the toboggans dug out.
There have been several fatal avalanches in the U.S. and Canada in the past few days. It appears that not everywhere in the States is snow less. For information on the 3 fatality's in the U.S. click here:

There has also been another avalanche related fatality in Golden B.C. Click here for link:
