Gorges+Island

Hi, my name is Kira. I am in the 8th grade at the[| Amigos School] in Cambridge. My class went to Gorges Island, an island in [|Boston Harbor]. I am doing this Wiki to talk about drumlin. Gorges Island and the other Boston Harbor Islands are drumlins.

We got to Gorges Island by taking a bus to Long Wharf then taking a boat to Gorges Island. The island is in the middle of Boston Harbor. It has a fort on it called Fort Warren. It was a union fort and prison during the Civil War. At Gorges Island, we studied drumlins by looking at each side of the island.

Drumlins are made of till, which is clay, rocks, dirt and some plants. They look like up side down teaspoons because they were dropped there by glaciers. This is how it happened. Glaciers picked up dirt and rocks. Then they moved into Boston. After that they moved/melted dropping the dirt and rocks a.k.a. till. It also created the Boston basin and isolated the islands. The till formed islands. After many years the weather has shaped them.

The north side of the island is really eroded and steep with big rocks. While the south side is like a beach with small rocks. On the trip we went to the north side to study till. Then we went to the north side to learn about rocks. After that we compared the two sides and learned about storms. I hope you have learned from our fun field trip to Gorges Island. I hope you go sometime.
