From this page, you'll find digitized pictures from mountaineering I've been doing. If not anything else is given, I have also shot the pictures myself.
The background image has also been made from a picture I took. When the snow is exposed to some wind, it forms the most fascinating patterns. You can have a look at the original if you like.
I've got more pictures on the disc than I've linked in the galleries, so you may also have a look in the indices generated by the server.
Don't be surprised by the fact that it seems to be more snow on some of the summer pictures than on winter pictures. It is due to the fact that at high altitudes, it takes a while before the snow melts away, so a more sensible classification would be to classify whether precipitation comes as snow or rain: After late September or October, it will usually snow in the mountains, while it rarely snows after May. But, then again...
