I have been on the air recently of NPR affiliate KNAU here in Flagstaff, to provide some context to the controversy regarding the age of the Grand Canyon. The first in-studio interview was with reporter Gillian Ferris-Kohl and you can listen to it here.
Today a piece aired from the Fronteras desk and reporter Laurel Morales. We walked along Grand Canyon's Trail of Time last week and discussed the recent controversy. You can listen to the report here.
