Everyone loves a party. Whether it’s 50 years of marriage, 25 years of a career, another year among the living, or another workweek among the gainfully employed, we humans gleefully celebrate that which we have accomplished or successfully put behind us.
And so it is with nature in Driftless Wisconsin; the place for a festive end-of-summer bash complete with colorful ornaments hung from branches and confetti streaming from the sky. We call this celebration the fall color season.
The color season represents a remarkable phenomenon; an avalanche of color from every tree top and hilltop, marching through every conceivable color of the spectrum. No one can predict when exactly this party will start; only that it begins in the unfathomable inner workings of a leaf. According to the US Forest Service:
Three factors influence autumn leaf color-leaf pigments, length of night, and weather, but not quite in the way we think. The timing of color change and leaf fall are primarily regulated by the calendar, that is, the increasing length of night. As days grow shorter, and nights grow longer and cooler, biochemical processes in the leaf begin to paint the landscape with Nature’s autumn palette.
A color palette needs pigments, and there are three types that are involved in autumn color: chlorophyll, carotenoids, and anthocyanins. During the growing season, chlorophyll is continually being produced and broken down and leaves appear green. As night length increases in the autumn, chlorophyll production slows down and then stops and eventually all the chlorophyll is destroyed. The carotenoids and anthocyanins that are present in the leaf are then unmasked and show their colors.
Despite this reasoned explanation and our general state of anticipation throughout September, fall color arrives with such splendor we find ourselves awestruck as if witnessing the transformation for the first time. We never tire of the celebration.
And the party has just begun.
I wake each morning to reddening Virginia Creeper unfurling from the trunks of elm trees across the drywash from our house; a flowering plant in the grape family and the first sign of fall color.
The basswood in our driveway shows a hint of yellow, the way we might dab paint on the wall to see if the color suits our taste. A walk in the woods reveals a scattering of early-fallen leaves underfoot; a sign of the thickening carpet yet to come.
Driftless Wisconsin celebrates this transformation in our own special ways. We like parades, festivals, craft fairs, and other activities to keep pace with nature. And there’s no shortage of opportunities.
The Gays Mills Apple Festival, normally the last full weekend of September, has been rescheduled for October 7 – 9. Main Street comes alive with a carnival, arts and crafts vendors, music, plenty of food, and a parade. And be sure to climb Highway 171 to orchard ridge for your annual supply of apples.
Prairie du Chien celebrates Octoberfest on Oct 15 to showcase our German heritage. The event features German food, drink, games, and music at St. Feriole Island’s Memorial Gardens; and a parade in the downtown.
Norskedalen Nature and Heritage Center near Coon Valley celebrates the haunted side of October with Ghoulees in the Coulees on October 27 – 29. Dress up in your scariest costume for a walk along a pumpkin-lit trail, complete with hidden goblins; trick or treat at historic homesteads; and gather around storytellers with a cup of hot apple cider.
This party will last a few weeks, until every leaf and party favor has dropped to the ground. Time enough for you to come join the celebration.
