Glacial melting and flooding occurs every year by the Skafta River in Iceland. As the water travels down towards the North Atlantic Ocean, incredible patterns are created on the hillsides. Rising lava, steam vents, or newly opened hot springs can all cause this rapid ice melt, leading to a sizable release of water that picks up sediment as it flows down from the glaciers.

Hundreds of tiny streams caused by glacier melt, merge together in the southern region of Iceland to form an outlet into the North Atlantic Ocean. Rising lava, steam vents, or newly opened hot springs can all cause this rapid ice melt, leading to a sizable release of water that picks up sediment as it flows down from the glaciers.
