Quaking aspens light up western mountainsides in autumn. They're also one of the best subjects for intimate landscapes year-round.
When aspens turn
In the Rocky Mountains, color usually peaks from mid-September to early October, starting at the highest groves and moving downhill over two to three weeks. Each clone — a grove sharing one root system — turns at its own pace, so a single slope can show green, gold and orange at once. A hard frost or windstorm can strip leaves quickly.
Where
- Colorado: the San Juan Mountains, Kebler Pass, the Maroon Bells area and Kenosha Pass. See the Colorado photography guide.
- Utah: the Boulder Mountain area and the Wasatch.
- New Mexico: the Sangre de Cristo Mountains.
- Arizona: the San Francisco Peaks near Flagstaff.
Photographing color
- Overcast days saturate yellow and remove harsh contrast under the canopy.
- Backlight makes leaves glow; look up into the trees.
- A polarizer cuts leaf glare and deepens the sky.
- A telephoto isolates patches of gold against dark conifers.
Trunks and patterns
White aspen trunks form graphic vertical lines. Use a telephoto to compress a forest of trunks, or try intentional vertical camera movement at 1/4–1/2 s for painterly abstracts (see abstract nature ideas).
Winter and spring
Bare white trunks against snow make minimalist images; fresh lime-green leaves in late spring are underrated.
