Ribbon lake - Wikipedia

WebRibbon Lake As a glacier flows over the land, it flows over hard rock and softer rock. Softer rock is less resistant, so a glacier will carve a deeper trough. When the glacier has retreated, water will collect in the deeper area and create a long, thin lake called a ribbon lake. The areas of harder rock left behind are called rock steps. WebIts formation begins when a glacier moves over an area containing alternate hands of hard and soft bedrock. The sharp-edged rocks that are picked up by the glacier and carried at the bottom of the glacier erode the softer rock more quickly by abrasion, thus creating a hollow called a rock basin. hbo tv shows 2019
