 Also on the Canadian side and entering the lower Stikine, like the Great Glacier, are the Mud and Flood Glaciers, which form the boundaries of the small Boundary Range, which is an eastern abutment of the range comprising the Stikine Icecap and marks the approximate boundary claimed by the United States prior to the Alaska Boundary Settlement of 1903.The Stikine Icecap area is also renowned for its technically demanding and dangerous peaks and spires of granite that have garnered comparisons as North America's version of Patagonia.Peaks of particular renown include Devils Thumb, Witches Tits, Cat's Ears, and the Burkett Needle.
