  • Mount Adams is a potentially active stratovolcano in the Cascade Range and the second-highest mountain in Washington.
  • Adams is a member of the Cascade Volcanic Arc, and is one of the arc's largest volcanoes, located in a remote wilderness 31 miles east of Mount St. Helens.
  • The Mount Adams Wilderness comprises the upper and western part of the volcano's cone. The eastern side of the mountain is part of the Yakama Nation.
  • Adams' asymmetrical and broad body rises 1.5 miles above the Cascade crest. Its nearly flat summit was formed as a result of cone-building eruptions from separated vents.
  • The volcano has a volume of 85 cubic miles placing it second only to Mount Shasta in terms of bulk among the Cascade stratovolcanoes.
  • The Pacific Crest Trail traverses the western flank of the mountain.
