Snowmobiling on Mt Adams A.G. Aiken Lava Bed

Kevin and I decided to give Mt Adams a try on Sunday. I wanted to see if we could get up onto the A.G. Aiken Lava Bed on the South side of Mt Adams near the boundary of the Yakima Indian Reservation. The A.G. Aiken Lava Bed is just over one mile East of the popular South climb trailhead at Cold Springs campground. The weather was beautiful with mostly sunny skies and a temperature around 30°F. We unloaded the sleds at SnowKing Sno-Park which is about 6 miles Northeast of Trout Lake, Washington off forest road 82.

We were surprised to only find a few other vehicles at SnowKing Sno-Park when we arrived. I was expecting a huge crowd due to the nice weather. There was plenty of snow on the trail and soon we were bumping along the extremely rutted trail up toward the A.G. Aiken Lava Bed on Mt Adams.

The snow softened up as the sun continued its assault on us, unlike a past trip to Mt Saint Helens where it was icy all day.

We rode part way onto the A.G. Aiken Lava Bed before stopping. I am chicken when it comes to avalanches, and I wasn't comfortable going any higher today. We ended up walking a bit higher just to find lots of exposed rocks. It wouldn't have been a fun ride after all.

We headed back down to the trail and continued to the border of the Yakima Indian Reservation. You can't ride into the reservation or up higher on Mt Adams where it is designated wilderness.

It was a great day. We didn't see anyone else out although we heard one other snowmobiler on a nearby ridge.
