The Grand Canyon

The Grand Canyon looks 10 times as big as it seems in photos, and it is 10 times as big as it looks. After >45 minutes of walking downhill at a steady pace of 2.5 mph, we were barely more than half way to the snow line, which was less than a quarter of the way down the canyon. The walk down to the bottom and back up to the top of the canyon does take most of a day. There were cliffs large enough so a small rock falling from the top would kill you if it hit. There were places where you could see the wreckage of old rockslides. When you are walking down you think you have covered a lot of distance until you look up, and realize just how small the distance you have covered really is.
