Photograph of north and eastern rim of Turbid Lake explosion Crater
Photograph of north and eastern rim of the 9400-year-old Turbid Lake explosion crater showing the primary explosion ejecta rim with a secondary explosion ejecta rim inside the lake-occupied explosion crater. Many, if not most, larger explosion craters have multiple explosion histories and are long-lived hydrothermal systems.
