This classic mountaineering book turns 50 this year, and to celebrate, The Mountaineers has morphed its time-honored tome into a handy deck of playing cards that are ideal for passing time in the tent.
When you tire of gin rummy or hearts, flip the cards over and bone up on hypothermia signs, lightning safety, knots, or rescue procedures. You can also get the original in hardcover for $40. $7; 4 oz.; mountaineersbooks.org
