An Unnatural Wonder

Our team spent 16 days rafting through the Grand Canyon. We interviewed scientists, government officials, river runners, Canyon guides and others.

Sunday: Glen Canyon Dam altered the flow of the Colorado River and turned its ecology upside down.

Today: On the Little Colorado River, scientists try to keep one of the Canyon’s last native fish from going extinct.

Tuesday: Environmental groups have argued that the only way to save the Grand Canyon is to tear down Glen Canyon Dam.

Now at azcentral.com: “An Unnatural Wonder,” our new documentary.
