Bit late Xmas and all,
Anyhoo. Talking about charitable "Click-Throughs"

SnowLands Network is an org that is all for keeping the back-country for human-powered skiers/snowboarders/snowshoers.
http://www.snowlands.org

If you're gonna shop at BackCountry.com or Amazon.com, you can get SnowLands a donation from those places

Just click on the green "purchase stuff" square, which'll take you here:

Any of you know of any more, snow related, good cause "click-throughs" ? Avy Forecasters Maybe ?
I see the Sierra Avi Center gets something if you get your discount Kirkwood lift ticket from REI.
