finding the snow cave(s) would of course be the best thing, but, depending on a lot of variables, if one's not there to look for it, but to climb the mountain, it might not be noticed. whiteout, climbing in dark, out of direct line of sight (stomping past not over)...who knows. you might see a snow-cave-like shadow and think 'well that's probably not it' -- for wahtever reason -- and if you're there to get the summit, rather than there to look for climbers in dire need, you just might not follow up as you would if you were there in search mode.
i'm just saying why not let SAR do their thing and 'go get some' somewhere else this weekend? (i know, sweatinoutliquor, that you're not the original poster of that phrase).
