In the Colorado Rockies ,the Aspen signal the arrival of Autumn.High up on the distant ridges,they create bright gold patches,and rivers of yellow and orange in the creek drainages.We've had our first snow,about six inches last Saturday,and as if in response the herds of elk are browsing the last of the summer sweet grass in my yard.I stack wood close to the back door,so it will be kiln-dry for the coming fires of October.I seek out my jacket in the back of the closet,and find a lost pair of sunglasses in the pocket.The grocery store has a huge stack of colorful candies,and masks of skulls and comic Frankensteins who leer at the shoppers.The window,open just a crack to the night air,sends in a cold current that casts a heavy spell of sleep on the dreamer,and whispers the promise of deep snow and moonlight.
