With my extended time in Amarillo, I discovered a real gem. Caprock Canyons is a Texas State Park and it is beautiful. In some ways it is similar to Palo Duro Canyon, but it has its own bison herd. In fact, this state park hosts the only official Texas State Bison Herd. They are huge and magnificent!

This bad boy was giving me the eye. I was scared taking the photo and ready to run if he started charging me!
The landscape has many red rocks. It reminded me as a combination of Sedona and Kanab. It is gorgeous.
After paying my $4 fee, the ranger told me about a couple of mountain bike trails. I drove around the state park and then stopped to ride a trail loop. The ranger told me there was one section I would need to walk my bike because it was very steep and rocky. She was correct. There was no way to ride down it. I crossed a creek 3 times and had some rigorous riding. I was exhausted when finished, but completely loved the ride.
The bison are open range in Caprock Canyons, meaning there is nothing separating you and the Bison. You are strongly urged to get no closer than 50 yards to any bison. That sounds like very good advice to me since they can weigh up to 2,000 pounds! I got out my telephoto lens to take a few pictures of these massive creatures. A couple that I saw had some intense horns, so I did not want to get too close!
