The easternmost tip of Endicott Arm nearly reaches the Canadian border. Like all the fords in this region, it was carved by glaciers during the last Ice Age which ended about 11,000 years ago. One either side of the fjord the steep, nearly vertical walls, rise to a height of about 370 meters or 1,200 feet. Sitka spruce and western hemlock trees manage to cling onto the rock faces, adding to the breath-taking beauty of the landscape.
