When the glacial period was occuring, the climate began to warm up slightly. As it warmed up, the glacier began to melt and stop moving. When this happened, huge chunks of the ice broke off from the main glacier. When the weather became cold again the ice began to move again, running over the huge ice pieces that had fallen off. The pressure, from the glacier, would push down on top of the ice chunks and grind them into the earth's surface. The huge chunks of ice were buried deep in the ground, and covered with the sand, rocks, and soil, that was under the glacier. When the glacier finally melted, the hidden ice chunks melted, too. The ground on top of the ice pieces, caved in and started to form the basin for the kettlehole lake. Some examples of these lakes are Ossipee Lake, Newfound Lake in Bristol, and Echo Lake in Conway. |
