1. Grand Canyon Facts

2. Length of the Grand Canyon The Grand Canyon is 277 miles long; 443 kilometers

3. How many km = 1 mile? 443km/277mi = about 1.6 km

4. Average width of the Grand Canyon 10 miles or 16 km

5. Approximate Depth The North Rim of the Canyon is approximately 1,737 meters (5,700feet) deep. About 5 Eiffel Towers would fit inside the North Rim 5,700ft/1,063 ft

7. Hiking the Grand Canyon It takes one full day to hike down the entire canyon. Hiking down and back up in one trip is not recommended because dehydration or hypothermia can occur.

8. It would take about one week to make a full length river trip in a motorized boat.

9. From the North Rim to the South Rim the Grand Canyon is about 12 miles long. A drive in the car from rim to rim would take 215 miles and 5 hours. 215 miles per 5 hours = about 43 MPH

10. In 1540 Captain Garcia Lopez de Cardenas from Mexico visited the Grand Canyon to look for Gold. John Wesley Powell was the first to explore the whole canyon

11. The 7 states fed by the Colorado River are… Wyoming, Colorado, Utah, New Mexico, Arizona, Nevada, California 7/50 x 100 = 14%

12. The Colorado River ranges in depth from 6-90 feet Shallower areas tend to have the most rapids, while deeper water tends to be calmer.

13. The primary reason for building the Glenn Canyon Dam was to prevent silt from building up behind the Hoover Dam.

14. The dam has actually had a negative affect on the ecology of the area because the water no longer floods low lying areas, the water is colder an native fish can’t survive the new colder water.
