Hubbard Glacier, Alaska

Just 30 miles north of Yakutat is Hubbard Glacier, the longest tidewater glacier in the world. The 8-mile-wide glacier is easily Alaska’s most active. The riptides and currents that flow between Gilbert Point and the face of the glacier, a mere 1000ft away, are so strong that they cause Hubbard to calve almost continuously at peak tides. The entire area, part of the 545-sq-mile Russell Fjord Wilderness, is one of the most interesting places in Alaska and usually visited through flightseeing or boat tours.
