A narrow canyon with tall, layered rock walls and a rushing stream of water flowing over rocks of various sizes.

Triangulation

This composition stood out to me because of the shapes. If you look closely, you can see many triangles present - which is a very powerful shape for photography. First, the foreground of black and yellow rocks form a triangle. Then, the two prominent rocks on the lefthand side of the frame are both sharp, triangular shapes that take the viewers eye through the scene.
