Kjølen

Kjølen is a geographical term primarily used in Norway and Sweden to refer to a long, elevated ridge or mountain chain that forms a watershed, separating river systems that flow in opposite directions. The most prominent example is the Scandinavian Mountains, often referred to as Kjølen, which forms the backbone of the Scandinavian Peninsula. This vast mountain range extends for over 1,700 kilometers and acts as a natural border between Norway and Sweden. The term "Kjølen" itself translates to "the keel" in English, likely due to the long, narrow, and raised shape of these geographical features resembling the keel of a ship. These ridges are characterized by high peaks, glaciers, plateaus, and deep valleys. They significantly influence the climate and hydrology of the region, dictating drainage patterns and contributing to the formation of numerous lakes and rivers. Historically, Kjølen has been a significant factor in transportation and settlement, often serving as a natural barrier and influencing trade routes and human migration. The ecological diversity is considerable, with distinct flora and fauna adapted to the alpine and subarctic conditions found along these elevated terrains.
