Named after founding WCCB member Dr. Carroll Block, the area consists of restored prairie uplands and wetlands as well as Winnebago River bottoms. An abandoned railroad right-of-way containing native prairie cuts through the middle of the area. There are also several winter-cover food plots. This area is popular with hunters seeking waterfowl, upland birds, deer, and wild turkey.

Located 2 miles north of Leland at the intersection of U.S. Hwy 69 & 9
