One hundred and fifty years ago, a group of explorers led by civil war veteran John Wesley Powell set out to document the canyons of the Green and Colorado Rivers. To commemorate the journey, a group of scientists have been retracing his steps this summer. Our partners at Rocky Mountain Community Radio spoke by phone with the trip’s leader during one of their stops.
