Laura Cheek – At Home in Glacier Bay
Some of the most studied glaciers in the world are found in Glacier Bay National Park located in southeastern Alaska. These expansive ice sheets cover approximately ten percent of the earth’s surface and hold eighty percent of the world’s fresh water, ninety-nine percent of which can be found in Greenland and Antarctica. Due to gravity’s pull, glaciers shape and scour the landscape moving land and vegetation great distances as they slowly slide downward toward the sea. This glacial movement has created rich farmland, vast deposits of gravel and sand, and concentrated valuable metals, depending on where they glaciers have traveled. Glaciers also create deep valleys and fjords, like the kind seen in Glacier Bay National Park in Alaska. Laura Cheek was a national park ranger at Glacier Bay National Park in 1996 when this program was recorded. As part of her job, she boarded tour ships in Glacier Bay to discuss glaciers, what they’re like and how they’re formed.
Laura Cheek recommends “The Island Within,” by Richard Nelson.
