The Rock River Archaeological Society (RRAS) was organized in 1998 for the purpose of studying and sharing with others the rich cultural and archaeological history of the upper Rock River area, including Horicon Marsh and extending throughout southern Wisconsin.

Meetings for RRAS are held on the third Wednesday of the month at 7pm at the Horicon Marsh Education and Visitor Center located at N7725 Highway 28, Horicon, WI.  Meetings are held April-September.  These meetings are open to the public and all are invited to join!

Rock River Archeological Society Programs for 2025
