Of all the region's natural wonders, the massive Hubbard Glacier has perhaps drawn the most attention during recent years. Accurately described only in superlatives, North America's longest tidewater glacier was spawned on the slopes of lofty Mount Logan, Canada's tallest peak. The frozen arm is a branch of a massive ice field that sprawls across the highland valleys between Logan and the surrounding mountain range. The active natural formation seems almost alive. Nicknamed the "Galloping Glacier," Hubbard moves faster than almost any other glacier on the continent. In 1986, the frozen river surged forward nearly 50 feet, sealing shut the entrance to Russell Fjord, trapping the marine life from the sea. As the ice-choked channel filled with fresh water, Yakutat residents began to fear their community might be lost in the rising flood, but just as suddenly as it had formed, the natural dam broke, and the water level subsided to safe level. More than 75 miles long, the glacier face is an impressive sight for passing ships. It is more than six miles wide at its widest point, and its tallest face towers 500 feet above Disenchantment Bay, a small section of Yakutat Bay.
