The place where a glacier stopped moving and dropped the rocks and dirt it was carrying is called a moraine.

Here's a breakdown of the different types of moraines:

* Terminal moraine: This is a ridge of debris deposited at the furthest point a glacier reached.

* Lateral moraine: These are ridges of debris that form along the sides of a glacier.

* Medial moraine: This is a moraine that forms in the middle of a glacier when two glaciers merge, combining their lateral moraines.

* Recessional moraine: These are ridges of debris deposited as a glacier retreats.

These moraines can be very large and can help geologists understand the past movement and extent of glaciers.
