Puff Island

What You'll Like :

This rugged island in Lake Superior is part of the Canadian Shield—with one important distinction. The island features a 10-metre-thick wedge of metasedimentary rock, called “Puff Island conglomerate”. Occurring along the northeastern part of the island, this wedge is of immense interest to geologists as it represents the only known occurrence in Canada of what is called the “Upper Osler Group Sedimentary Sequence.”

Park Facilities and Activities: The reserve, which is only a small area of the island, is without facilities and camping is not permitted.

Location: In Lake Superior, 40 km south of the town of Nipigon.
