The snow from the previous day and night had left some of the buttresses looking a bit more wintry today. We decided to take advantage of this and try something mixed. The fiacaill looked the best place to head for, so Invernookie was the target. Dave and Colm led the first 2 pitches between them while I climbed alongside. I then switched into the system to lead the trickier upper section so the Colm and Dave could experience something a little more challenging. We topped out and came back down into the corrie to look at some more ice screw teaching, by this time the temperature had shot up and the buttresses were very quickly turning black again. After getting wet in the heavy sleet in the corrie we headed out, a good day to finish the course.
