Colorado Quaking Aspens in Fall

From Jim Zornes: "The train runs about 5 months out of the year and is worth the $35-$40 ticket. Cheapskate me & "mama" rode for free though. One of the mining companies bought it for the day and we had about 150+ guests with us."

More on Quaking Aspen: "Most individual quaking aspens are tall, slender, graceful trees, not known for their massive proportions. Their light bark color and "fluffy" branching pattern contribute to the illusion of small size, but quaking aspens can become large on favorable terrain." - From Native Trees for North American Landscapes - Sternberg/Wilson
