Grand Canyon National Park
Teamwork in the Natural World (wmv)
Ranger Minutes are short audiocasts or videocasts in which a park ranger shares interesting stories and information about Grand Canyon National Park.

 
In the natural world, when plants and animals benefit each other we call it a symbiotic relationship. Here at Grand Canyon National Park, we have lots of examples, including the relationship between yucca moths and yucca plants, between tassel-eared squirrels and ponderosa pines, and between badgers and coyotes.

THE INNER GORGE OF THE GRAND CANYON, 1200 feet (366m)  

Did You Know?
Within the Grand Canyon, the rugged, V-shaped Inner Gorge rises darkly from the Colorado River. The broad shelf above it is the Tonto Platform, which spreads like a green blanket across both sides of the canyon. The Inner Gorge achieves a depth of over 1200 feet (366m)
