Built in 1893, and relocated to it's current position in 1918, the Chicago Harbor Lighthouse marks the entrance to the Chicago Harbor, and ultimately the Chicago River. At the time, this harbor was the most important on the Great Lakes, and the busiest( in season) than any other in the country.

Interested in the unusual looking plants of Cowles Bog, Chris stops to capture some photos of the huge fiddleheads found here.

A group of visitors slide down one of the sand dunes on Central Beach. Not a good idea - for a lot of reasons, but erosion is the main concern, followed by impalement by a hidden branch.
