Pilot Knob Bog as a Habitat

The purposes of this paper are to introduce some of the physical characteristics and to summarize the geological and recent history of a northern Iowa Sphagnum bog. The marshy portion of Dead Man\u27s Lake, Pilot Knob State Park, was referred to as a bog by L. H. Pammel (1928) and described as a sphagnum mat by Grant and Thorne (1954). The park is located on the Hancock side of the Hancock-Winnebago county border in sections three and four of Ellington township. It is four miles east of Forest City
