I defy you to find better single-track classic sking in SE Iowa right now. Broke all trails today in virgin snow of the best quality. Any ski is now usable here. This is a hidden gem, so very few if any walkers will be out there anytime soon. If no readers of this report go out there, it will probably be as I left it next week when I go again.
Trailhead:

Fantastic soul skiing. This is not for those who like tights and want to just cardio themselves into a lather going in circles--those folks can stay at Ashton. This is for the classic skier wanting excellent glide, rolling hills, and a wonderful nature experience. If your order of priorities are 1. To Be Sublimely in the Woods, 2. To Have Fun, 3. To Get Some Exercise, this is for you.
Skunk River:

There are several loops of trails that range from riverside bottomland to hardwood blufftops to creek-carved valleys. Tracks today included coyote, bobcat (sorry, real bobcat, not cougar), turkey, deer, rabbit, possum, coon, mouse, and raptor. Woodpeckers of all sorts and songbirds abound. Also barred owls, who were curious about two bipeds in the winter woods and came by for a look. Big suckers. Eagles hang over the Skunk River.

Directions: HWY 1 south to Brighton, keep right on HWY 1 through town. About a mile west of Brighton is Fir Ave. Turn right. When the road ends in 3.5 mi., you're there.
