TOWN OF WIOTA - Blackhawk Memorial Park in Lafayette County, is fast losing its status as the best-kept secret in the state.Preserving 120-acres of natural forested countryside along the Pecatonica River - and a surprising piece of state history, the park has been placed on the Wisconsin State Register of Historic Places and is now waiting for national certification. "This will keep it as primitive as it is now, forever," said Sally Kahl, secretary of the Friends of Woodford Park, the group responsible for maintaining the county-owned park.But Kahl said the group also wants the park's recognition to bring more people to southern Wisconsin.Currently used for recreation, the park has long been known as the site of the Battle of the Pecatonica, the Battle of Bloody Lake or the Battle of Horseshoe Bend, during the 1832 Black Hawk War.The battle was not the largest military action of the war, but it made Henry Dodge a notable figure in Wisconsin. He became the first governor of the Wisconsin Territory in 1836 and, eventually, a U.S. Representative and Senator.
