It’s been a mild autumn so far with very few hard freezes. As a result, the fall color season continues even at the higher elevations. Last week we rode our mountain bikes on the Arizona Trail from FR418 south to Snowbowl Road. This is one of my favorite sections of the Arizona Trail because—among other reasons—it passes through several large stands of aspen trees.
Aspens typically grow in large clonal colonies derived from a single seedling. Thus, each stand or colony of aspen have a strong tendency for their leaves to change color at the same time, while a nearby stand may change either earlier or later.
