A great place to park for trails off Minaret Summit. However the ranger station is open from 9:00 am-5:00 pm during operation season. It is a fee area & also offers a shuttle bus during operation season.

The Obsidian Dome and its neighbors Glass Creek and Deadman Dome all erupted in early fall of 1350. Scientists were able to date this last volcanic activity based on tree rings. In this eruption, magma flew into large amounts of groundwater which led to massive explosions that formed the nearby Inyo Craters.

Volcanic activity is very intense in the nearby Mammoth Lakes region. Obsidian Dome is the natural site that illustrates it perfectly. Discover these volcanic phenomena by taking this path.

This trail seems to be rather new since you can find it in digital maps, but not necessarily in paper maps of the region. There is a good chance that some parts of the trail are still snow covered even in early July. Route finding skills are sometimes useful.
