Forty-two small explosion craters have been identified on the surface of the Big Obsidian Flow. In four of these craters parts of large spherical bubble-like cavities as much 50 feet in diameter have been found.

The crater at this waymark is the easiest of these caves to reach as it is near the end of the Big Obsidian Flow interpretive trail. Remember though that hiking off the established trail can be dangerous due to the obsidian which is a natural form of glass and can be very sharp.
