The cross section across the Jeptha Knob astrobleme is a representation of what the rocks beneath the surface of Jeptha Knob look like. It dramatically illustrates how the unit of rock shown in pink in the center of the astrobleme has been pushed upward. This is the geologic remnant of the uplifted rebound structure in the center of the crater. Geologists think the structure was formed around 425 million years ago, during the Ordovician Period.
