Royal Gorge
The Royal Gorge was forged over thousands of years by the Arkansas River slowly eroding granite in southeast Colorado. The canyon is approximately 10 miles long and up to 1,250 feet deep.
The Royal Gorge Bridge, pictured here, is 955 feet above the river, making it the highest bridge in North America. You can walk or drive across it. I did both and it is a bit nerve racking!
