This isn't really a great photo, but I heard some comments about canyons being claustrophobic. Which is definitely true some of the time, but not all of the time. Although that log solidly wedged 30 feet up might cause one to consider what this looks like during a flash flood.
Since I'm already posting photos of questionable quality, here's a canyon selfie. I know you're all jealous of my high-class canyon duds!
