Fifty years of mountaineering tips, gleaned from the pages of the seminal wilderness-safety book Mountaineering: Freedom of the Hills, are now available in a deck of playing cards. The 52 illustrated safety refreshers cover everything from reading cloud formations to building a snow cave. And the deck will come in handy, of course, if you actually need to wait out a storm in that snow cave. Just make sure you know a full house beats a flush before betting your down jacket. $7; mountaineersbooks.org
