Kevin killed it. Great instructions and interesting facts about the area, the glacier, and geology in general.
As for the format of the tour, it was the perfect amount of work (we like active tours) to make for a satisfying tour. Kevin made sure we all knew safety procedures and overall you'll be in great hands.
The lake, the glacier, the waterfall, and the surrounding mountains were all beautiful. The scenery was very dramatic and a great example of what Alaska has to offer.
