Yosemite Valley Forest, Autumn. Yosemite National Park, California. November 4, 2007 © Copyright G Dan Mitchell

I’m always intrigued by the combination of the strong verticals of the tree trunks (often interrupted by the diagonal of a fallen tree or two), the filtered light coming through the trees, and the warm tones of the leaves and needles on the forest floor interspersed with boulders and rocks that likely fell from the Valley walls many years ago.
