Science for Lunch: Alaska Dreaming (I): Land Sculpted By Ice

Many visitors come to Alaska for the glaciers. So, what are glaciers and why is Alaska such a special place for glacier formation and continued good health? How do glaciers create fjords? How fast do glaciers travel? Also discussed will be glacier erosion and moraines, why glaciers form crevasses, glacier calving, and why glacier ice is so blue. While the theme is ''what is that all about,'' the many examples are all from Alaska's major glaciers and fjords that are such tourist attractions.
