After a perfect day on Mount Joffre I woke up the team at 03:30 on Sunday morning for an attempt at my 400th peak – Mount Marlborough. We packed up camp under a clear, cool sky and soon found ourselves under the approach gully up the north west side of the mountain. The snow was fairly hard, but there was a punchy crust if you went looking for it. We knew that we had to get up and down the steep south face to the upper ridge before the morning sun started to hit it. There was recent avy debris in the upper bowl so we knew that parts of the slope wanted to slide.
