Erosion on Earth and Mars: Mere Seepage or Megaflood?
May 28, 2008 / Posted by: Daniella Scalice
Researchers from NAI’s University of California, Berkeley Team have a new study in this week’s Science focused on Box Canyon in Idaho. Incised into a basaltic plain with no drainage network upstream, and approximately 10 cubic meters per second of seepage emanating from its vertical headwall, the canyon is a veritable poster child of groundwater seepage erosion. But this new study posits evidence that the canyon’s formation was caused rather by catastrophic megaflood 45,000 years ago. Their results imply that flooding of this kind may have caused similar features on Mars.
