 That's Como 4's Kelly Koopmans. And part of Mount St. Helens, the crater rim, in fact, has collapsed. The U.S. Forest Service says a cornice, or a piece of ice that extends beyond the edge, broke off and fell more than 1,000 feet into the crater below. This has made the top of Monitor Ridge highly unstable, and hikers and mountain climbers in the area are urged to use extreme caution.
