We spent an extra day in Amarillo just so we could go and see this canyon. It is about 30 miles south of Amarillo and even though its the second largest canyon in the country it isn't well known. It was very beautiful with a lot of the same colors as the Grand Canyon -- it's just not as deep. You can drive to the bottom where there are a couple of campgrounds and picnic areas.
The drive down to the bottom is a little scary with a 10 percent grade -- not sure I would want to take a big RV down it but we saw a few large rigs -- even towing cars down at the bottom.
If you look closely at the picture that is a little washed out -- in the middle of the picture is the rock formation that is the most noteworthy in the park. It is called lighthouse rock.
We left Amarillo and headed over to Oklahoma City and just missed all the rain in Texas. The I-40 within the Oklahoma City area is a terrible road. They are replacing it but not fast enough -our truck rides pretty smoothly carrying a load but even loaded we were bouncing pretty good.
