Earth Notes

About This Section
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.

  • In the late nineteenth and early twentieth centuries, the timber industry was drawn to the Colorado Plateau’s extensive pine forests. And African Americans played a big part in that industry.

    Bison are among the most emblematic animals of the American West. Many Indigenous peoples relied on them for survival. Some, such as the Zuni, have oral histories of hunting them and performing a Buffalo Dance ceremony. Bison are known primarily as Plains animals, but historically they did extend into the Southwest.
