Boardwalks on Isle Royale

This photo was taken along the Rock Harbr Trail near Three Mile Campground about a week ago. A group of backpackers heading out into the backcountry for 4 or 5 days was coming down the trail toward me. I was standing on the edge of a swamp that the broadwalk bridges. You can see that the ferns in the swamp have only recently emgered -- and in late June! It is summer, but late spring would be a better description of the some of the micro-climates that are near the shores of harbors and lakes in the national park. The many boardwalks on the island are important in protecting the swampy areas of the island, which have there own partucular charms, especially concerning the varieties of flowers and plants that do best in low-lying damp areas.
