The third port we stopped at was in Skagway. One of the best things on our trip was the helicopter ride. We took a 20 minute flight up to the middle of a glacier. They gave us ice boots with metal cleats on them and we took a walking tour. The bottom picture was taken from the helicopter obviously but it looks like we getting close to the ground when actually we are still very high up. The dark lines on the ice that look like tire grooves are actually streams of boulders that the ice has pulled off the mountainside as it slowly crawls out of the mountains. I will post another picture that show just how big those boulders are that make up the lines.
