Yosemite Voices 1: Soundscapes

Episode 1
Soundscapes

This episode is based on an interview with Kurt Fristrup PhD, the senior acoustic Specialist with the National Park Service’s Natural Sounds Program in Fort Collins, Colorado. He talks about the effect of noise on predator-prey relationships, animal communications, and on human physiology. Fristrup reveals some of the findings on the acoustic health of Yosemite as well as some interesting discoveries made possible through recordings made in the wilderness.

El Portal Boulder Bar

Did You Know?
At the east end of El Portal, just west of Yosemite National Park’s boundary, changing river gradients, glacial history, and powerful floods have created a boulder bar with boulders much larger than typically found in such deposits. This is no ordinary boulder bar, however, for it contains massive boulders over a meter in diameter and weighing many tons.
