Earth Notes

Wednesdays at 7:30 a.m. and 5:32 p.m. and Saturdays at 9:34 a.m.

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.

Wildfires in the West have gotten bigger and more intense over the last 40 years. The amount of land area burned has increased six-fold. On the Colorado Plateau, fires strip away plant life and open up a window to the past, revealing information from thousands of years ago.

Many people are aware that Flagstaff and environs played a central role in the race to land a man on the Moon in the 1960s. The Apollo astronauts trained amid the volcanic landscape surrounding town—the best re-creation of the Moon’s pock-marked surface to be found on Earth.
