Terminal Moraine

• Terminal moraine is a ridge across the valley and is made up of glacial deposits which is unsorted.
• As the glacier moves downhill, it acts like a bulldozer, pushing sediment in front of its snout as it goes.
• On temperatures rise, the glacier melts, losing power and depositing the moraine.
• Terminal moraine marks the furthest point that the glacier reaches.
• Once the ice has retreated, the terminal moraine can often form a natural dam, creating a ribbon lake.
