Quizplus · Accepted Answer

Eskers are long, winding ridges of sand and gravel that were deposited by meltwater channels below or within a glacier. They are typically found in areas that were covered by glaciers during the last ice age. The meltwater streams flowing through and beneath the glacier carried sediment and deposited it in ridges as the glacier retreated.
