Smooth shapes big and small


The ferry trip out to Vinalhaven offers views of beautiful, smoothed bedrock islands, waterfowl, harbor seals, and lighthouses.  We went to view igneous intrusions, but I was pleasantly surprised to see glacial striations and smoothed bedrock bumps.  Perhaps I’m easy to please.  The circular erosion pattern in the image below shows the location of granite intrusion pipes.
