Hiked and climbed to the natural arch feature off of Mitchell Trail in Los Alamos.
This arch is unusual since it occurs in volcanic rocks that form the Jemez Mountains. Natural arches are normally found in sandstones such as those in Arches National Park. The last part of the hike up to the arch is pretty steep. Some actual climbing is required. The arch is called Phoenix Arch by many people in Los Alamos.
Good view of the Los Alamos townsite from the arch. LANL Casa Grande can be seen in the center of the last photo. Also note Omega bridge.
