Alluvial Fan

Rocky Mountain National Park
Photograph by Tom Atwood
This photo of the Alluvial Fan in Rocky Mountain National Park was taken at sunset, but the glow you see along the mountains is not the sun. In fact, the sky was completely overcast on this evening. Instead, the glow is from the artificial lights of nearby Estes Park reflecting on the clouds. The Alluvial Fan was actually formed by a massive rock slide in the park years ago. Shutter: 30 seconds; Aperture: f/4.5; ISO: 800; Focal length: 18 mm.
