  • 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.
"Six of us were stuck in a cave for three hours on 8/4/18 about an hour below the Lunch Counter. Severe hail storm with lightening. No warning. We were instantly wet and cold." - blindskov, Aug 5, 2018
"Left Spokane the day before at 2PM and cruised into Cold Springs around 8:30PM. It was a Tuesday so much fewer people than the trip reports that I’ve read before…maybe 15 cars. The next morning I started on the trail around 6AM, wishing I’d woken up earlier. The ascent was spectacular. 5mph winds, no clouds, 40ish degrees. The only downside to the elements was the haze from the British Columbia fires. I never got a glimpse of Hood or MSH, and only a peak of Rainier (once I summited). I knew it was going to be warmer so I decided to go without ice axe (trekking poles only) figuring if an" - zachmitch, Aug 9, 2017
"long slog up, mostly boots and crampons above the shoulder. snow was crappy, hard runnels and variable up high, with a few thousand feet of decent conditions on the SW Chutes lower down where it had softened enough. lots of traversing and up-climbing over various ridges, constantly traversing left on the descent to make it back to the south side route and trailhead, definitely made the descent lots of work and less enjoyable" - hauteroute, Jul 1, 2017
"Solo, 21.9km return with 2297m of elevation gain. Started with sunrise at 5:16am; 5hrs up, 2 - down, 8 hours car-to-car. Had whiteout between 2600m and ~3000m, twice. Plus a thundercloud on the way back, had to run down from South Butte." - alexp, Jun 9, 2017
"Another Cascade volcano ski weekend (I can't get enough of these!)...a short sleep leading into an after work drive to Rogers Pass for another short sleep in the car in the rain, and then working from Vernon before driving 9 hours with buddy to Trout Lake, Washington for 2:30am arrival and 3 hr bed down in the tent. Up at 6am and walking up the logging road at 7:30am with 2.5km of walking until skis on and another 1km to trailhead and then the long slog up the south rib. Buddy wasn't feeling it so turned around half way and I continued up. WTF I have to go down after the first false summit!!! " - alexjoseph, Jun 3, 2017
