The Giant, Strange Rocks of "Pebble" Beach

I continue my rockhounding trip around the Lake Superior Circle Tour, this time hitting one of my last stops along the Ontario side of Lake Superior. Wacky unakites and strange metamorphic rocks.
Pebble Beach, Ontario is within the town of Marathon, near Pukaskwa National Park and a couple hours from Sleeping Giant Provincial Park.
Important: While Pebble Beach is not within the confines of the protected parks nearby, please respect the sign asking visitors not to take rocks with them and leave what you find at the beach.
