winter tips
2 points if I may.
Dont let the door close behind you. By that I mean basically dont lose your descent route and dont let weather force you to be pinned down. When ascending it is critical to continually look back at the route you will be descending (given you not doing a loop) dont wait until your descent to make out the route, many times in the winter the same route you ascended looks remarkably different on descent, by studying landmarks,ie boulders, wierd looking trees, ice formations, these may be vital to "linking" up your desent route in bad visability. While climbing in bad wether is very possible, there is a fine line to be reached here, make sure to monitor conditions as you climb, watch the cloud cover, cloud density and moisture content, these are all factors that could "sock" you in and make travel impossible. Ive seen conditions on Washington drop to 5 ft visibilty, thats thin and makes finding your decent extremely difficult, you could miss your ridge and end up on the edge of a ravine very quickly, which can lead into av slopes cliffs and such.
One last point that I always have stressed, you must have the abilty to descend VERY fast if the above stated conditions present themselves, Ive been with other climbers who stress a slow and safe descent to prevent injury, this may seem like a good idea, but speed in deteriating conditions can be the difference between, a beer and a pizza or a horrible bivi above treeline, imo.
