The Anchorage Museum gathers together some of Alaska's most dramatic traditions and transforms them into exhibits and attractions that allow them to come alive in various multi-dimensional presentations. One of the museum's galleries features 600 Alaska Native artifacts that are on loan from the Smithsonian Institution. Some of these items include ceremonial masks, battle armor and waterproof clothing made from the intestines of a seal. The museum features 80 exhibits that include an aurora machine, a marine animal touch tank and the very popular earthquake shake table. New additions include a planetarium and an Alaska Native contemporary art gallery.
