Newberry Volcano is the largest volcano is the Cascades. It has erupted numerous times over the last 400,000 years and created a unique landscape of cinder cones, obsidian flows, chunky pumice flows, a mile long lava tube and two caldera lakes.

The monument has two major sections that are miles apart from each other so I’m making two separate posts.
