About this image

Except for the loss of its ring of ejecta, the crater at the leading edge of a streamlined island in Kasei Vallis shows no hint of the catastrophic floods that passed by it. Kasei Vallis is one of several major outflow channel systems that were active over 3 billion years ago. The intense floods scoured the landscape, eroding craters and producing streamlined islands. But in a close-up view, the evidence for these floods is not apparent. This is true of the most similar terrestrial example, the channeled scablands of eastern Washington which also were formed by a catastrophic flood.
