Stark borders and protects part of the Pigeon River, one of the few unaltered and undredged rivers in northern Indiana. A walk on the trail near the river reveals that the water is tea-colored from the tannin found in the surrounding wetlands. A prominent feature of the property is an oxbow of the Pigeon River. This oxbow usually contains water. The resulting u-shaped pond is used by wood ducks for feeding, breeding and raising their young. If you don’t see these ducks, you may hear their “meep-meep-meep” call.
