Taken as we reached the summit of the Cumbres and Toltec Railroad. The line runs between Chama, New Mexico, and Antonito, Colorado. The summit is near 10,000 feet. The aspens (and others) were displaying remarkable colors.

Some of the blur is the motion of the train, some of the blur is bokeh.

For the Sunday Challenge, this is a nice way to enjoy the change of seasons. Winter will be along soon enough. At least the conifers in the background will stay green throughout the seasons.
