As geologists we travel the planet looking for cool stuff. Obsidian Dome took us by surprise. While the obsidian on offer may not match that of southern Oregon's Newberry Crater, Obsidian Dome is an easy drive of no more than 10 minutes on a very well maintained gravel road from SR 395 within a stone's throw of Yosemite and Mammoth Lakes in the eastern Sierra Nevadas. ANY vehicle can do the drive to the Dome. The real issue is how much obsidian do you want to bring home?! Anyone with a hint of geologist's blood coursing through their veins will want to check out Obsidian Dome.
