The Crater Glacier (also known as Tulutson Glacier) is a geologically young glacier that is located on Mount St. Helens in the U.S. state of Washington. The glacier formed after the 1980 Eruption and due to its location the body of ice grew rapidly unknown to the public for nearly 20 years. The glacier once contained ice caves in the smooth ice before the 2004-2008 volcanic activity.
