Field Trips

Sadly, because of the pandemic, we are currently unable to offer field trips. We know that these are one of the most popular offerings of IMMG, but it has not been possible to arrange leaders and trips in the uncertainty of virus restrictions and public concerns about group activities.

 

Here is a link to a “virtual field trip” to Anderson Ranch Dam, South Fork Boise River and Smith Prairie:  https://docs.google.com/presentation/d/15Ok75PRs76P_hDoxw8YT_KhV-Vs8dkoB/edit#slide=id.p12
