The Indian Army continues to control all of the Siachen Glacier and its tributary glaciers. India controls all of the Siachen Glacier itself, including all tributary glaciers. Leavenworth sits on the terminal moraine of that glacier. Lateral moraines are parallel ridges of debris deposited along the sides of a glacier. A bay formed by a glacier is a fjord. The park is larger than Yellowstone, Everglades, Glacier, and Grand Canyon national parks combined. It is larger than the Yellowstone, Yosemite, Grand Canyon, Glacier, and Olympic National Parks combined. It is farther east than all the rest of Washington's volcanoes except Glacier Peak. Crevasses form because of differences in glacier velocity. This is the southeast ridge of the peak, rising above the Godwin-Austen Glacier. This was largely due to acceleration of ice streams such as Pine Island Glacier. The mine is located within what used to be a small equatorial mountain glacier. Lateral moraines are formed on the sides of the glacier. The permafrost/glacier line generally starts around . Cirques are where ice begins to accumulate in a glacier.
