My partner and I camped at Boston-Sahale col Saturday night (all the Sahale permits were taken) and planned on carrying over the next day. I guess we were one day late, though. We retreated to the tent around 8pm when it started raining hard. The noise of the wind and rain kept me from getting any real sleep, and when our alarm beeped at 3.30am, it was still nasty out. We went back over Sahale at 9am, still in a whiteout.
The camp at the col is pretty cool -- a single tent platform with a short rock wall. I left my stove and pot on a little sheltered alcove nearby (a great kitchen) and it didn't blow away overnight. The view would probably be incredible, too. We got only a very short glimpse of Ripsaw Ridge and Buckner through the clouds, but it was awesome! I definitely want to try again and camp in the same spot.
