Lake Champlain Basin Studies

We had a scavenger hunt to see different types of erosion. We went on this field trip to see how the islands were formed. We also were there because we were learning about the basin and how the rain would come down from the mountains, go through the rivers and into the lake. Along the way we found fungus, a dead tree (above) that could be a home for a squirrel or chipmunk. In 50 years it could become soil. By Carson, Colby, Cody, Thomas & Sam.

The railroad was suported by marble and granite. The train used to come and take people from South Hero to Burlington. Were the bridge is gone its caled the cut. By Carson, Colby, Cody, Thomas & Sam.


Our class went to Allen Point. While we were there, we learned how the lake changed over time. We walked and walked until we got to the bench and talked about Lake Vermont. Almost 14,000 years ago Lake Vermont was formed. The melting glacier left behind a body of fresh water. Lake Champlain covered the land from the Adirondack Mountains to the base of the Green Mountains. The Champlain Islands were covered in water and Snake Mountain and Mt. Philo were likely island. Then Lake Vermont drained into the Hudson River. By Lucia, Kip, Griffin and Rachel


Almost 13,000 years ago the Champlain Sea was formed. the world wide melting glaciers caused the sea level to rize. Then the glacier moved back north and alowed the sea to flow in through the St. Lawrence Vally into lake Vermont. The Champlain Sea was half as salty as the Atlantic. Workers in Charlotte found a beluga whale fossil left over from the Champlain Sea. By Kip, Lucia, Griffin and Rachel.


Did you know that we live in a big basin? Lake Champlain Basin is its name. The bathtub shaped basin was carved by the most recent glacier. The Green and Adirondack Mountains are the edges of the basin. If the mountains were not there the lake would flood out. We hope Lake Champlain will stay for many years to come. By Ethan, Hannah, Christian and Chris.

Our two classes were lucky enough to have Mrs.Hickey come teach us how every day products can pollute the lake. Mrs.Hickey showed us a model of a town like South Hero(above). She demonstrated with her model how everyday products like oil, pestisides, and manure can travel to the lake. We learned how large the amount of bad materials that is getting to the lake is. We also learned how we can use fewer of these bad materials. Thank you Mrs.Hickey! By Ethan, Hannah, Christian and Chris.
