What type of feature is Hatt Hill? Briefly describe how it was formed. Use a red colored pencil or pen and circle several other of these features on the map.

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?
