This ice field—named for the Baltimore university—numbers among Alaska’s most picturesque; it’s also one of the planet’s few advancing tidewater glaciers. On a clear day, sunlight ignites the turquoise blue of its 76-meter-tall face (called “a snout”), which is backed by the snow-gilded crags of the Fairweather Range. Stretching 20 kilometers in length, this river of frozen water flows more than three meters each day and has a cave where it kisses the ocean.
