text: Doing some geology similar to what the astronauts did on the moon, we figured out that the cinder must only be about 3-4 feet deep as the shallower craters up to about 3 feet deep did not show the orange-tan ejecta while the deeper craters more than about 4 feet deep did and the orange-tan ejecta is just the underlying soil of the region.
