Top leaf-peeping hikes near south Denver
By Lexi Reich
As autumn approaches, the hills and mountains near Denver transform into a canvas of gold, orange and red hues. One of the best ways to experience this natural spectacle is through leaf-peeping hikes, particularly to witness the aspens in all their fall glory.
Understanding Aspen Leaf Color Change
Aspen trees are renowned for their vibrant fall colors, which result from a fascinating biological process. According to Dr. Dan West, the forest entomologist with the Colorado State Forest Service, aspens flush leaves in spring using sugar stored from the previous season. Throughout summer, these trees produce sugar through photosynthesis, facilitated by chlorophyll, the pigment responsible for the green color in leaves.
However, as days shorten in fall, the production of chlorophyll halts, unveiling other pigments in the leaves. Xanthophylls produce yellow hues, carotenoids create oranges, and anthocyanins bring out reds and purples. The formation of an abscission layer, which cuts off the leaf from the tree’s nutrient supply, allows these pigments to emerge. Optimal conditions for vibrant fall colors include sunny days and cool (but not freezing) nights. Variations in weather, such as early frost or drought, can impact the intensity and duration of the colors.
“It’s not an exact science year to year, but we can tell how the viewing season might unfold with predictors of moisture and storm outlooks as the viewing season approaches,” West says.
As you plan your leaf-peeping adventures, remember to check current conditions, dress appropriately and bring a camera to capture the season’s beauty.
