Where on Earth? - August 2011

Clues for August 2011:
1. These deep grooves were carved by a glacier into the limestone bedrock as recently as 10,000 to 12,000 years ago. Hard boulders embedded at the base of the ice ground through the softer limestone to scour out the grooves.
2. The limestone formed about 350 million years ago, when the region was under a clear, warm, shallow sea. It contains a rich abundance of Devonian fossils, including crinoids, brachiopods, bryozoans, cephalopods and corals.
3. The grooves are located on an island that was first settled by Native Americans nearly 1,000 years ago.
