Flagstaff, AZ – Earth Notes: Vanishing Silence

Have you noticed the world getting noisier? Even in wild places the sound of silence is becoming scarce.

Earth Notes - Fossil Creek Revisited

Flagstaff, AZ – Almost three years after Arizona Public Service decommissioned the Childs and Irving power plants on Fossil Creek, a restoration success story has blossomed.

Fossil Creek starts from springs below the Mogollon Rim in central Arizona.
