Alpine glaciers are glaciers formed in the mountains. Continental glaciers are formed during ice ages and are large, expanses of ice. The high altitude or the troposphere and â¦ the constant snow that is packed together and turned to ice is what forms the alpine glaciers high in the mountains.Unique landforms created by alpine glaciers are: U-Shaped Valleys, Hanging Valleys, Cirques, and Aretes.Unique landforms created by continental glaciers are: Kettle Lakes, Outwash Plains, Drumlins, and Finger Lakes. They both leave moraines and till in their wake.nique landforms created by alpine glaciers are: U-Shaped Valleys, Hanging Valleys, Cirques, and Aretes.
