Girl Scout Event: Earn the Geology Patch

September 19, 2020 @ 10:00 am - 12:00 pm

Join Girl Scouts and the Idaho Museum of Mining and Geology for a fun day getting outside and engaging with the Earth!  Girls will take a tour of the museum where they can explore different types of rocks and learn about the history of mining in Idaho.  They will then go on a hillside hike to Castle Rock (.7 miles RT) to experience Idaho’s geologic features first hand.  Please arrive ready to hike with appropriate hiking shoes and water bottle.

This is not a drop off event. Parents/Guardians or troop leaders must stay for the full activity. Please no tag-a-longs; please leave non-participating siblings at home.
