Icebergs and their smaller siblings, “bergy bits” and “growlers,” boom like thunder as they calve away from their parent glacier and when they do, they reveal the remarkable turquoise that lies within. It’s turquoise because the densely packed ice of the glacier squeezed out every other color in the spectrum.
Yes, the glaciers are indeed melting at an alarming rate; Montana’s Glacier National Park may be without its glacier in less than 20 years. Almost 70 percent of all the freshwater on Earth is held in the polar ice caps and glaciers. That’s something to think about.
