The Mono-Inyo craters produced explosive eruptions and effusive lava flows. The pumice layers above the bottom of the pen originated from the South Deadman vent of Inyo Craters about 600 years ago. Interbedded finer layers record brief pauses during the course of the eruption. Photo by Larry Mastin, 1986 (U.S. Geological Survey).
