When the sky is clear, focusing on what the last light of the day is hitting is often the optimal plan. Last light typically falls on high-elevation features, and Rock Cut in Rocky Mountain National Park has that qualification.
A Colorado 14er, Longs Peak, also captures the day's last light. Framing this mountain between the Rock Cut features results in what you see here.
Join me in RMNP this September. I have an opening or two for the Elk Rut in Rocky Mountain National Park Instructional Photo Tour.
