Can anyone provide an exact location for me to put in my gps for this?
Fun hike, it was cool to see the rocks change beneath your feet, we actually spent about 3 hours following the 'trail', before turning back.
So cool to see but don't try to climb off trail that stuff is sharp! I made the mistake of trying to follow my boyfriend when he wanted to explore and cell and cut myself lol. Oops.
Have updated this review... One of the best places to see a hill of solid obsidian - beautiful black glass - although it just looks like rock until you break it open - don't remove it (it is sharp and will cut you). Wear good shoes. 11 miles north of Mammoth Lakes up I-395 from the I-395 and CA-203 intersections, take a left on Obsidian Dome road, and it is 2.7 miles up Obsidian, Glass Flow, and Glass Creek Rds. Dirt road to parking area; hike starts down and to the right of the dome and up a gravel bulldozed hill that takes you into the cone at the top. Really good description here: http://volcanoes.usgs.gov/volcanoes/long_valley/long_valley_sub_page_19.html [along with directions - coordinates - about 37°44.810' N, 119°01.305' W]. Another good hike (more scenic) is Panum Crater near Mono Lake starting near the South Tufa trail [http://volcanoes.usgs.gov/volcanoes/long_valley/field_guides_panum_crater.html].
A great hike for geology nuts and people who like sharp things. The trail isn't really well marked past a certain point, but that just means you choose your own adventure. Sweeping views off to the north and northeast at trail's end - even a glimpse of nearby Lava Beds National Monument on clear days. This was a tool source used by natives for hundreds of miles around, but nowadays more or less in the middle of nowhere, so it's good for a bit of peace and quiet.
