More snow poles

From the recent blasé comments, I don't think that everyone appreciates how deep (and dangerous) the snow can be. At the leading edges, snow densities are high and depths can reach two metres. In the photograph here, Markkus and Toivo provide a good comparison for scale. The orange posts that they are placing along the array are 3 metres tall.

Posting along the drifts.

When the snow builds up like this, it can crush structures through the sheer weight of it. Packed snow can be quite heavy, as the destructive winter testing in 2011 showed.
