August 19th, 2017 at the WEMS Thunderdown in the Underdown

Location: Underdown Main Parking Lot on Copper Lake Road between Irma and Gleason

Course: A 33 mile single track loop that combines the best of the old school with zippy machine built renovations.  Ride past 4 lakes, 5 bermed boardwalks and 64 hills all the way to the Prairie Dells overlook and back.  Guaranteed that there will be something you haven't seen before.  Mechanical updates are in progress to keep your momentum high.

Great Weekend

Ski trails are groomed.
Snowshoe trails are tracked and in good shape.
The Big Bog Loop was a different kind of fat bike ride today.  Dog Lake was a viable ride too, and Mist Lake is an adventure as always.

The Prairie Dells loop from Heineman Road  is incredibly fast right now.  The forecast looks good for more great riding, but give it a break if it gets too melty.

Melting, but not Melted

Underdown trails are soft, but there is still plenty of snow.
  • Ski trails are tracked.
  • Snowshoe trails have tracks all the way around the Mist Lake loop with new sign posts in place across the Long Bog. 
  • The Prairie Dells loop is waiting for a freeze to be a great ride again.
UNDERDOWN TRAIL WEEKEND next weekend has a great forecast.
Saturday 10AM: Guided snowshoe hikes from Copper Lake Road from one to four hours.
Sunday 10AM: Fat bike ride from Copper Lake Road.
Underdown ski trails and Prairie Dells fat bike trails open all weekend.

Tons of Snow

Copper Lake Road:

  • Ski Trails: Groomed and tracked beautifully, except for Loop Road as of Thursday.
  • Snowshoe Trails: Tracks at least to Dog Lake.  Lakes are solid and bog bumps are filling in.  Challenging fat biking by this weekend.
Heineman Road Dells Loop:

  • Great snowshoeing right now!
  • Marginal fat biking on snowmobile track.  Drifting above the marsh.  Grooming will resume Saturday once the track sets up enough to allow the machine to pull something.  Sunday looks promising for a nice ride.

Northwoods Chapter of the Ice Age Trail Alliance Snowshoe Hike

Saturday January 28, 2017
10:00 A.M. 

The Northwoods Chapter of the Ice Age Trail Alliance will host  a
guided snowshoe hike in the Underdown area of the Lincoln County Forest on Saturday,  January 28, 2017 starting at 10:00 A.M.   Meet at the  Underdown Recreation Parking Lot on Copper Lake Road.

Come and enjoy the wonderful landscape created by the Great Wisconsin Glacier about ten
thousand years ago.  A UW geology and geophysics professor described the Underdown as a
“world class hummocky feature” of glacial topography.  In simpler terms, the area has swamps,
lakes, bogs and hills abundantly.

The snowshoe trail layout and design has been done by chapter member, Chris Schotz. The trail
is well marked and packed.  Hikers can chose between distances of one to four hours depending 
on your ability, experience and endurance.  The trail is “moderately difficult”.  Bring your
snowshoes, drink and weather appropriate clothing.

Hot cider, hot chocolate, cookies and a blazing fire will await you after the hike.  There is no charge for this event.  Donations to the chapter will be accepted.
