Mt. St. Helens is located in southwest Washington State, just to the west of the Cascade Crest. Roads access the blast zone from the west (Johnston Ridge / Toutle River) and the east (Windy Ridge), but the roads do not meet. Another road leads to the area south of the mountain where you'll find other interesting areas like the lava tubes of Ape Cave.
