Glacial groove marks. Small iceberg floating near a rock face showing glacial scarring. Glaciers are large masses of ice that form high up in mountains and flow downhill. Their large mass presses down on loose rocks,causing them to scour deep grooves in the bedrock,as seen here. Photograped at the Puerto Moreno Glacier,Patagonia,Argentina | |
