On Tuesday we went to Mount Desert Island (MDI) to look at erosional glacial features. At our first stop, we learned how to determine which way the glacier flowed through this area over a “roche moutonnee”. Then we headed to Somes Sounds which is the only fjord on the east coast of the US. We had lunch, enjoying the view gouged out by a two kilometer thick sheet of ice. Many tourists who also stopped would ask if we were in class or what we were doing because they noticed our SJC van. We would explain the ESS trip and many of them would respond, “Oh, this is a really cool hands on experience.” Next on our agenda was Jordan Pond (formed by a push moraine) which gave us a great view of The Bubbles, which we would soon hike to the top of.
As you would expect, North Bubble and South Bubble have a bubble-like shape. We geared up for this small but slightly steep hike up about 700 feet on the South Bubble. Once we reached the top, the view was spectacular and Dr. Erikson said, “Take out your yellow notebooks! This is where we are going to have class today!” We had an exercise to draw a topographical map of the mountains and landscape around us. We could see Jordan Pond and the ocean in the far distance with mountains surrounding us on three sides. On our way down we had to conveniently stop at Bubble Rock. Bubble Rock is another touristy attraction on top of the South Bubble. It was placed high up on the edge of South Bubble by a glacier near the end of the most recent Ice Age (about 20,000 years ago). After everyone got pictures of Bubble Rock we headed down and decided to do a tourist thing and stop at Thunder Hole.
Thunder Hole is a natural rock inlet where waves will hit it and it will sound like thunder. When the waves are really large it could splash up to 40 feet with a roar of thunder. When we were there the waves were small causing no thunder noise. After anxiously waiting to hear thunder with no luck we headed out for a delicious dinner in Bar Harbor.
