Hole-in-the-Wall Glacier. Aerial view of the Hole- in-the-Wall Glacier cascading over a cliff. The helicopter next to the glacier is taking tourists on a flightseeing tour of the glacier. A glacier occurs when more snow falls than melts. Over time,layers of fallen snow become compacted,forming ice. The mass of the ice in a glacier flows under the pull of gravity. As a glacier moves,it removes material from one location (erosion) and carries it to another (deposition). Photographed in Juneau,Alaska,USA | |
