Roll up your sleeves and dig with us into our site's buried history. Come prepared to get dirty, learn a lot, and personally play an important part in the quest to expand our historical understanding of how the Fort Winnebago Indian Agency—and particularly the blacksmith shop—functioned in the early 1830s.To dig, a membership is required. Pre-registration for dig time(s) is recommended. Kids get a free t-shirt, too, while supplies last.
