Earth Notes

The Colorado Plateau is one of North America’s human and environmental treasures. Ancient cultures have called this land of sun-baked deserts and lush mountain landscapes home for centuries. Earth Notes, KNAU’s weekly environmental series, explores the Plateau by telling stories of the intricate relationships between environmental issues and our daily lives.

Rooted in science and wrapped in human interest, the two minute long segments encourage listeners to think of themselves as part of the solution to environmental problems. Upbeat and informative, the program tries to foster hope and dampen despair about the environment, and motivate listeners to become more conscious and informed stewards of the Colorado Plateau.

Smoky Mountain--The Kaiparowits Plateau

It's almost like you're looking into the nostrils of hell.
Michael Collier and Rose Houk

Don't try the Kelly Grade in a rainstorm. When this steep stretch of the Smoky Mountain Road is wet, its mud surface is impossibly slick. Stay in granny gear, keep a tight grip on the wheel, and hope that nobody else is coming the other way. There's no guardrail and that cliff next to your tires drops hundreds of feet straight down.  The shale gives way to sandstone when the road straightens out on top of the Kaiparowits Plateau.
