At this stop, scavenger hunters ventured across and under… the Hennepin Avenue Bridge. This bridge is named after Louis Hennepin, who was a 17th-century explorer who first saw Saint Anthony Falls. Finding these falls was an important historical event because it is the only waterfall across the entire Mississippi River. This bridge connects Hennepin Avenue, which is in downtown Minneapolis, to Nicollet Island. Teams ventured across the bridge to take in the sights of the river. However, we gave them the challenge to also venture under the bridge. Once under the bridge, they had to take a photo of a team member pretending to be a troll who was asking another team member to pay a toll.
