3rd Knowl Ski today. Cooler temps have firmed up the snow surface however it is not yet supportive to skis. Was difficult skiing on all aspects 1200m down to 700m at the base. No argument for a 2nd lap. Did not venture higher due to poor visibility. Foggy with a light ridge wind out of the south. Snowing less than 1cm an hour down to the base. Ski pen was a resistant 20cm.
