The feature numbered 4 in the lower right of the figure is a terminal moraine, which is a ridge of rock and debris deposited at the end (or "terminal") of a glacier. This feature is formed as the glacier reaches its maximum extent and then begins to retreat, depositing the material it has picked up along the way.
