In southwestern Colorado lies a deep narrow canyon befitting a National Park. Stop to see it if you pass near Gunnison, Colorado. We finally made it on our SLC trip in 2005 with the Bergseths.
Like the Grand Canyon this one is probably more beautiful seen from the bottom. I'd like to do it one day.
You need to see it to appreciate the awesome splendor of this gorge.
