Lots of smoke! Couldn't see a whole lot. Couldn't see Mt Gordon... sweet day though, found quite a bit of snow remaining on the approach to the col - made for some tough crevasse mazes, had to do a fair amount of probing. Summit both Olive peaks. Took the front of St Nic on the way down, and went down too far and couldn't get back on the glacier (too thin). Should have stayed high to get back on it, going down the cliff bands was a bit annoying. Water was good.
