Glaciation+in+Cambridge

__Introduction__
Hello, my name is Jonah and I go to the [|Amigos School]. I am writing this wiki as a school project and to let people know about my topic: glaciation in Cambridge. Our grade went on a field trip to the Maynard Ecology Center where we learned about evidence of glaciation.

__Description__
On our field trip, we went to the Maynard Ecology Center (MEC) and [|Fresh Pond]. We were supposed to take a school bus, but it never came. We walked to a bus station and took a city bus there. The MEC is a building next to Fresh Pond, so we got information by walking around Fresh Pond and doing an experiment in the MEC. Fresh Pond is a 155 acre reservoir with a 162 acre surrounding park and a 2.25 mile hike. It is the city water supply.



__Summary__
When we went to Fresh Pond and the MEC, we studied evidence of glaciers in Cambridge. We went to Fresh Pond first. Fresh Pond is a **kettle pond**. The retreating Laurentide Glacier created it. There, we saw and walked next a **moraine**. A **moraine** is a ridge of dirt and rocks that is pushed by the glacier. Then, we walked on an **esker**. We learned that an **esker** is an elevated lump of **deposits**. The river under the glacier leaves it when it dries. After that, we did an experiment at the MEC. There were glacier tables that had different experiments on each. Mine was a “glacier” (ice and dirt) with water getting poured on it. We watched how it melted and the dirt got **eroded** and **deposited**. The field trip was fun and educational.
