Part of Alaska's allure is melting. But it's not all bad news for the 49th state's glaciers. While most of the more than 100,000 glaciers in Alaska are thinning, retreating or stagnating, Johns Hopkins and Margerie glaciers are actually advancing, fed by abundant snowfall from the Fairweather Range.
These are just two of the icy wonders in the 3.3 million-acre Glacier Bay National Park in southeast Alaska. The last of the bay's four glacial periods began about 4,000 years ago, leaving today's glaciers in its wake.
Take a sea kayaking trip out of park headquarters at Bartlett Cove to get a closer look at these icy Alaskan phenomena, or see the wild expanse from above on a flight seeing expedition. If you're lucky, you'll see a moose or bear swimming across the bay.
