Near Mono Lake there is a volcanic cone called Panum. Panum is not a dormant volcano. This area is monitored by geologists for any signs of activity that might signal another eruption.
There is a 2.1 mile loop trail around the Panum crater. My son and I hike a portion of this trail. Mono Lake and the Sierra Nevada are visible from portions of the trail.
Large chunks of obsidian are common along the hiking trail.
In addition to the large chunks of obsidian there are common layered rocks of obsidian and pumice scattered around the area.
A portion of the trail is visible in the lower portion of this image.
This information sign is posted at the trailhead.
This wraps up my March visit to California.
Thanks for following,
