Passasjoen

Passasjoen, also written Passasjøen, is the name given to several lakes in Norway. The name means "the pass lake" in Norwegian, combining pass (mountain pass) and sjøen/sjø (lake). The definite form Passasjøen (with the -en ending) is used in Norwegian; English transliterations sometimes render it as Passasjoen.

Geography: Because multiple lakes bear the name, geographic details vary by site. In general, Passasjoen lakes are located in or near mountainous or hilly terrain and form part of local watershed systems. They are typically small to medium-sized freshwater lakes and may lie at higher elevations than surrounding lowlands.

Ecology and usage: These lakes belong to Norway's freshwater ecosystems and are subject to national environmental regulations. They commonly support freshwater flora and fauna typical for inland Norwegian lakes. They are used locally for recreation, such as fishing, boating, and hiking along shorelines, and may be part of scenic or tourism-oriented landscapes.

History and name origin: The name aligns with historical travel routes that traversed mountain passes; lakes at or near passes often served as landmarks, water sources, or resting points for travelers.
