This is a somewhat close-up view of a glacier as it meets the water from our recent Alaskan trip. The big blue columns of ice form a wall at the water's edge. The best I could estimate the size is that the columns are about 200 to 300 feet high. Periodically, a sliver will fall into the water and create a big splash. You can see that splash at the bottom center of the photo -- I think that splash is about 30-50 feet high. The process is called calving.
The mountains slide past our cruise ship as w3 sail the passages near Skagway, Alaska, on our recent vacation, My wife, Linda, is holding on to her hood because of the brisk, cold wind. Two things to note about this photo 1) the glacier in the middle of the picture sliding down the mountains ( you can slightly see the blue color of the ice). 2. the guy walking in shorts toward us -- he must have been doing the ice bucket challenge or something. Oh, by the way, this is from the first week of August.
