=Georges Island--Drumlin Formation=

Hiiiiiiiiiiiiii and welcome to our. . .space!!! Now quick, read and memorize this!!! (Just kidding) :D
Hi, my name’s Ruby and I’m a student at the [|Amigos School] in Massachusetts. I’m doing this WIKI about Georges Island, and how it becomes a drumlin. I want other people to know how interesting it can be; we even got to go on a field trip to Georges Island to examine the beaches for erosion and deposition that eventually lead to the creation of a drumlin.

Like I said, our 7th grade class took a field trip to Georges Island, one of the Boston Harbor Islands. It has two beaches, the north and south beach. The south beach is made of mostly sand and very small pebbles, and the north beach has a broken seawall, a bunch of huge, broken rocks, and a big wall of till (all the stuff inside a drumlin). We studied the tides on both beaches and the wall of till at the north beach to figure out how the water helped with the erosion and deposition of the land.

The point of our field trip was to learn about drumlin formation at Georges Island, and we definitely did learn a lot. On the south beach and north beach, we examined and noted the slope of the land. The north beach is very steep because of the exposed wall of till that takes up most of the beach, and the south beach is almost flat, not steep at all. This told us that powerful tides have been eroding the north beach and forming the steep wall, while nothing is damaging the south beach’s land. Another thing we did was examine the north beach’s exposed till wall. We saw that the rocks and pebbles on the south beach were the same as the smaller parts of the huge, destroyed rocks on the north beach. This led us to learning a 3rd thing: the eroded particles of till were being carried from the north beach (by the water) and being deposited on the south beach! This helped us understand the cycle of drumlin formation, and now all of us know: tides on Georges Island erode and deposit land to help create a drumlin!

Above is a picture of our class examining the broken seawall (front & left) and the wall of till (far right) on the North Beach.



Geology

Prior to 1833 the island consisted of two drumlins with elevations of 48 and 64 feet, similar to the topography of the east head of Peddocks Island. The fort was tucked in between the two drumlins and the island substantially regraded. The current highpoint of 50 feet exists at the top of the fort’s ramparts.

The information above was found [|here] on the Boston Harbor Islands website. :)
