How Trees Grow

Sunday, January 12, 9:00 AM – Noon

Enjoy the forest but want to learn more?  Jim Reinartz will explain the special ways trees grow.   This event will start in the classroom and then we will venture out to the woods.


Winter Hike and Chili Potluck

Sunday, January 26

Winter Hike 1:30 – 4:30 PM

Winter presents the opportunity to explore the interior of the Cedarburg Bog.   Jim Reinartz (Field Station Director Emeritus) will lead the annual hike into the heart of the Bog. This is a 4-mile hike, and weather or snow and ice conditions can make this hike challenging.  In the past we have hiked in bitter cold, on a warm day with wet slush over the ice, in deep snow, with no snow at all on very slick ice, and when we were lucky, with a little snow over solid ice.  If ice conditions in the Bog are not safe, we will hike in the uplands instead.  The Field Station website (http://uwm.edu/field-station/) will be updated several days prior to the hike with snow and ice conditions.

Chili Dinner    4:30 PM

The Friends of the Cedarburg Bog are hosting a Chili Dinner Potluck after the Winter Hike.  The Friends will have lots of chili ready as well as beverages.  Bring a dish to share – side dish, salad, dessert – all are appreciated and enjoyed!  It’s a wonderful way to finish up the hike but please join us for the potluck even if you don’t plan to hike.

Suggested donation for the Hike and Dinner is $5
