Photos of aspens and autumn color, mostly in the San Juan Mountains. This fall was a very colorful one, with the aspens showing off much oranger and redder colors than usual.

(I scouted out and photographed this vantage point in September 2012; since then this has become an iconic and often-photographed perspective, which is why I feel obliged to toot my own horn and mention that my photos here are the originals!)
