Moraine is a glacial landforms which results from glacial movement. As a glacier moves down the mountain it leaves behind debris of dirt and boulders.
Look below the glaciers in these photos. It looks like a river of rock. This is the debris left from the glaciers above which have retreated for the summer months.

We continue our study on mountain glacial landforms with the arête.
An arête is formed by two glaciers scouring away rock on two sides of a mountain. The result is a thin ridge of rock which separates two U-Shaped valleys. Weathering further erodes the rock thus shaping and sharpening the feature. Arêtes can also be formed when two cirques erode.
