New Grand Canyon study on Science Friday

March 12, 2008

This morning on the way to work I listened to NPR’s Science Friday podcast (I’m a bit behind and still catching up). It was about the recent paper in Science discussing new dates from speleothems in the Grand Canyon region that are interpreted by the authors of the paper to push the age of canyon formation from ~6 million years to ~17 million years.

Andrew over at About.com has already posted about this and has some great links to relevant information.

The reason I mention this is because a retired USGS research scientist who has worked on the Grand Canyon for decades called into the show and really took the author of the Science paper to task on their conclusions. It is quite entertaining … the Science paper author sounds a bit taken aback and stumbles a bit in trying to defend their interpretation. I enjoy contentious scientific debates.

Give it a listen … you can download/subscribe to Science Friday here.

    that was a great debate. I agree the study author was not expecting such a strong counterargument and the media by and large have missed on reporting on that.
