When we go out into nature with our cameras, our attention is grabbed by geometry, whether we realize it or not. We are fascinated by patterns, lines, arcs, angles, circles and ellipses.
In this particular image, the first thing catching my attention on that rainy morning in Mount Rainier National Park were the tall trees standing at attention next to that somewhat-arc of a swiftly-flowing stream.

Great lines in the trees, Rebecca, with beautiful contrasting horizontal water elements. Terrific work.
