Our AuSable River - How healthy is it now?

Discerning the Health of the AuSable River. THURSDAY, AUGUST 19 7:00pm-8:30pm

The last several years, volunteers have organized under a Gahagan Nature Preserve initiative to monitor the health of the upper AuSable River Watershed. The group has collected aquatic bugs (Benthic Macro Invertebrates), using what we know about various species to learn what type of water quality we have and to provide a baseline for the future. Join Tom Dale, Gahgan's Environmental Educator and Project Leader for an enlightening presentation at Roscommon' s AuSable River Center, 211 N. Main Street.

Karsts

Wednesday of this week finds Geologist Ty Black coming to the cabin at 7 PM to tell us about karst formations in northeast Michigan. You'll find these sinkhole features interseting - bet you climb in the car soon after for the quick drive to the Presque Isle County area.

Bonus! Ty is the expert when it comes to area's karsts.
