No guest this week friends, instead we turn the radio show into a classroom and join a lecture given by legendary regional geologist Wayne Ranney as he discusses how the Grand Canyon was formed and the endless debate over how old the Grand Canyon actually is. This was from a recording on the South Rim of the Grand Canyon at the Shrine of the Ages courtesy of the Grand Canyon Association.
There are some great visuals in his presentation too, so if you would like to watch it instead of listening you can head over to the video on the Grand Canyon Associations Youtube Channel.
