Where would you like to go?
This place was detailed on a recent NOVA episode on PBS - they now think the canyon may have been the result of a catastrophic flood from an ice damn breaking somewhere up river (probably the result of a volcanic eruption). It is a really awe inspiring place - off the beaten path, not too crowded, and beautiful. There are great campgrounds here, a nice visitor center, and long hiking trails that go from the canyon floor to the rim for amazing viewpoints. For those that have a hard time getting around there is a road all the way into the canyon with paved walkways leading to viewing areas. Well worth the stop if you're even in the area!
