Newberry National Volcanic Monument, Nature reserve in Deschutes County, US.
Newberry National Volcanic Monument is a large protected area in central Oregon featuring volcanic fields, lava flows, cinder cones, and two lakes within the Newberry Caldera. The landscape displays multiple forms of volcanic activity, from dark lava surfaces to vast underground tubes of hardened lava.
People have lived and worked in this volcanic landscape for thousands of years, leaving behind traces of their presence. Federal protection came in 1990 to preserve the unique geological formations and the largest uncollapsed lava tubes found in Oregon.
Native American tribes used volcanic materials from this landscape to make tools and gather food for generations. Rock art scattered through the region shows how these communities lived and worked in connection with the volcanic terrain.
The site has twelve marked trails of varying difficulty, ranging from short walks to full-day hikes that require good fitness. Access is easiest during warmer months when roads and paths are fully open and snow is not blocking the way.
The Big Obsidian Flow is a striking black glass surface created by a volcanic eruption around 1,300 years ago that covers a large expanse. Walking across this dark glassy plain reveals how sharp and brittle the volcanic obsidian can be underfoot.
