Even the geomorphology is bigger (faster) in Texas!

This week in Nature Geoscience, Michael Lamb and Mark Fonstad report the incision of Canyon Lake Gorge, Texas, during a single dam-release flood event in 2002. This well-constrained flood event moved metre-sized boulders, excavated ~7 m of limestone and transformed a soil-mantled valley into a bedrock canyon in only ~3 days! Not quite a natural flood event, but quite spectacular and informative all the same. View Canyon Lake in Google Earth here.
