A bit of icy history






In this place a person can watch one of the earths most fundamental geological processes in action as 12 tidewater glaciers calve into the sea. The bay was inhabited long ago by the Tlingits until the glacier surged forward forcing them across the Icy Strait to Hoonah. By the time Captain George Vancouver arrived in 1794, Glacier Bay was encased in ice, just a small indentation on the chart. The glaciers have receded 65 miles since Vancouvers time, although today some advance, others retreat, and a few hold their ground.
