Slept very well after my afternoon of skiing. Got up early, had breakfast, and joined a group for a guided hike on Sólheimajökul Glacier. Drove about 2 hours southeast of Reykjavík. Mostly 2 lane road covered in ice and snow – the only indication one is on a road are the side markers and the packed snow from previous traffic (glad I didn’t rent a car). The guide showed us how to use the crampons and ice axes, then we headed onto the glacier for a 3 hour hike. It takes about an hour just to climb up onto the glacier. There we could see the blue ice often with steaks of ash from volcanic eruptions in years past. The weather would change from sun to clouds to snow seemingly within minutes. The glacier was covered in fresh snow but we could see many crevasses and other features of the glacier. It was a great experience for someone from California who rarely sees snow.
