Is this area well drained or poorly drained and swampy? Explain your answer.
A sinuously curving, narrow ridge of coarse sand and gravel is called an esker. Eskers form along the channel of a meltwater stream that flows beneath a glacier, in an ice tunnel, or between ice walls beneath the glacier. As a glacier retreats, the steep-sided esker is left behind in a pattern roughly parallel to the path of the glacier.
What will be an ideal response?
Poorly drained, as shown by the many swamps.
