[NMCAVER] The age of the Grand Canyon using Caves

[Ray Keeler]

Hi All,

Here is the link to today's NPR Science Friday piece on Dr. Victor Polyak's
interview on the age of the Grand Canyon using cave speleothem dating.
 Since Victor is a long time member of the Sandia Grotto and the funding 
came
 from the National Science Foundation, it has relevence.  The piece takes
 about ten minutes.
