As I sit on the beach at Wolf Point in Glacier Bay, the orcas play and the tidewater glaciers shimmer in the long summer light.
Red Mountain is reflected in the ripples of the tidal lagoon.
Everything is so peaceful. Amazingly, we're on our ninth straight day of sunshine, in an area that's lucky to see the sun six days in a whole year. I've led this trip before, but it's never been quite like this. In fact, just like teaching a class, it's different every time. I teach mathematics at Mission College in Silicon Valley, and I recuperate in the summer by leading groups in Alaska for Sierra Club National Outings.
