Swiss web cam map
Here is a neat map showing Swiss web cams via Dave Hayes, another snowboard blogger.
It is not as comprehensive as my favourite web cam site, Snoweye, but it is a good graphical representation, at least for Switzerland.
If you click on the locations on the European Map at the bottom you can get similar maps for other countries e.g. Italy http://www.wetterklima.de/cams/italiencam.htm
I also really like this one of Cervinia
