Another planet

It is beautiful from the bottom, but hike to the top and be transported to another planet. It is a short easy hike but bring a hat because there is no shade.

When my grandparents owned a lodge in Mammoth this was my grandpa's favorite place. We always stop and poke around anytime we head that way. It's beautiful in itself and the trees and surrounding area are very pretty and peaceful. It's an easy drive off the highway so a good place to take a break.

If you've been to the moon then skip this stop. If not then you'll really enjoy the quick side trip to Obsidian Dome. The climb and exploration is about 90 minutes total - longer if you have time to linger. Amazing view of the rocks and quite enjoyable views with very few people. Kids will enjoy going here and there... More

Creek is dry if you look between the rocks where the fly's are you will find some moss and tiny eyedropper of... More

Include a stop at this dome as part of a day trip. Children will get a kick out of the formation. Short trail. Moderate steep hike to the crater. Not handicapped accessible. Plan 30 to 45 minute exploration.

Spend a few hours checking out this geological site and you won't regret it. No entrance fee. Just follow the signs to the dome. A bit of a bumpy road to get here, so watch out if you have a rental car. Hike up a short but steep path and you can walk around on the top of the dome.... More

Fantastic example of Obsidian rock. Easy drive to it and you can park within a few feet of thousands of Obsidian rock of all sizes.

An interesting diversion for about 30 minutes or so if travelling south from Mono Lake towards Bishop, CA. Access is up a dirt road for about 2 miles into the forest. An interesting site to view the Obsidian (Volcanic Glass like rock) at this geological site.

This area of the Obsidian Dome is quite a ways off the road but is worth the drive at least once in a lifetime. Another amazing natural sight and site.

It is located about 8 miles north of Mammoth Lakes, just south of June Lake, off Highway 395 — via a 2.7 mile dirt road to a... More
