Kärlbäddar

Kärlbäddar, a Swedish term, translates to "cauldron beds" or "kettle lakes" in English and refers to a specific type of glacial landform. These are often circular or oval depressions found in glacial till or outwash plains. They are formed by the melting of buried ice blocks that were left behind by retreating glaciers. As the glacial ice melted, the overlying sediment would slump down, creating a depression.

The size and shape of kärlbäddar can vary significantly, from a few meters to several hundred meters in diameter. Their depth also varies, and many fill with water to form small lakes or ponds, often referred to as kettle lakes. These bodies of water can sometimes be ephemeral, drying up during periods of drought. The sediment composition within a kärlbädd often reflects the materials that were deposited around the buried ice block.

Kärlbäddar are common in glaciated regions worldwide, not just in Sweden. They are considered important indicators of past glacial activity and provide insights into the dynamics of ice retreat. The presence of these features can also influence local hydrology and ecosystems, with kettle lakes often supporting unique plant and animal communities. They are a common feature in landscapes shaped by continental glaciation, such as parts of North America and Northern Europe.
