THE Page 4 July 20, 2006 Pinhook Bog Continued from Page 3 The property that is now owned by the IDNL was once owned by the Jackman family. Jennifer report- ed that the Jackman’s picked and sold the bog blue- berries from their farm stand on Wozniak Road. Their house was where the parking lot is now, and the family allowed trekkers to see the bog. According to history archives at the Michigan City Public Library, those who ventured into the bog (when the property was still under the stewardship of the Jackman’s) had to rough it. There was no boardwalk, so one had to slosh through mucky water to reach the sphagnum carpet. If you are considering a visit to Pinhook Bog, be aware of certain limitations. In addition to having to reserve a spot on a scheduled trek, you will be descending two short flights of stairs into a gated area.

Cattails, ferns, arrowroot, and other plants live here, but not past a certain point. You’ll be warned about the poison ivy along the descent, and about poison sumac. During our visit, the vegetation—mainly thick growths of blue- berry bushes, makes the boardwalk seem narrow.
