Hi wrecker,
My friend Ted and I climbed most of Olympus in February 1995. We went up the Hoh trail, and hit snow about OGS. We camped a couple of miles further up. The next day we went to glacier meadows and camped there. The trail above elk lake has some exposed avalance chutes, and the trail was filled in at a steep angle by heavy snow. We were a little intimidated, and roped up and used crampons and ice axes for some parts of the trail just before glacier meadows. It would be a long ride down into the deep drainage below. There did not seem to be a high chance of avalanche being triggered by us, so that was ok. We went up during one of those 2 week high pressure arctic fronts. It was quite cold at glacier meadows, about 4200 ft. We did not need skis at that time because the snow was so consolidated. We camped two nights at the glacier meadows to scout the route. The next day we went up the moraine, and dropped down it and crossed the blue glacier. The crossing was easy, no crevasses showing, and no rocks on the climb to snow dome. We ascended to the top of snow dome and ate lunch on the top of the hut over by panic point. Should have gone on to west peak since it was not that far away, but the days are short, and we had done enough. I feel sure that it has been climbed in winter, but know of no one who has done it. It just is a long climb, 18 miles into glacier meadows, and a bit of time on the mountain. We had a great time though, and you should give it a try if the snow conditions look good. Try a climb during a high pressure window. On the way down, when we hit the bad part of the trail, where the snow concealed it in the avalance slopes, we just walked across without ropes, I guess we were more complacent and it didnt seem so bad.
