What a stunning day, blue skies and sun all day with no breeze. Linda & Chris were with me today on their two day winter skills. We headed up to Coire Mhusagain below Stob ban and went through the basics of walking on snow and ice, axe & crampon techniques and axe arresting. It was very warm in the sun (must remember the shades tomorrow!). Great view into Stob Ban's North face and a quiet spot. There is recent avalanche debris at the bottom of South & North gullies (see last pic). Sub zero temps again overnight and a blue sky day again tomorrow. Wonderful.
