The little stacks of rocks on the big rock -- they're what's used to mark out the hiking trails. In a lot of places, you'd get lost if they weren't there, because the trails aren't obvious. The little photo on the right is a closer look.
I come to a spot where there are thousands of little rock stacks, so I jump on the bandwagon and add my own. All I can find lying around are little pebbles.
Here's a better look at all the little piles. The holes in the rock in the background are filled with little stacks, too.
Navajo arch. The furthest point in my hike. (There's a little more to do, but I'm already more than 2 miles from my car, low on water, and enough is enough!)
Me in the Navajo Arch.
Inside the Navajo Arch is like a cave without a roof.
Inside looking out.
Heading back down the trail. Yes, this is a trail.
