This is apparently one of the favorite hikes in the park.  It is about 2 1/5 miles round trip to the Red Cathedral and it is an amazing, ever-changing hike.  You can walk around an outcroping of rock and see completely different colors and geologic formation. We kept wishing we could show Grumpy (and ask him questions). I had to select from all the wonderful pictures Bob took and there are still way too many. There was just too much to see.
