ペンケトー


概要


アイヌの言葉で、ペンケトーは上の沼地という意味です。雄阿寒岳の東山麓にあるこの湖は、北端にある唯一の流出河川でパンケトーと繋がっています。


昔々、ペンケトーとパンケトー、阿寒湖は一つの大きな湖でした。しかし、およそ1万年から6千年前に起こった雄阿寒岳の火山活動によって、もともとの古阿寒湖は、一部が埋まり、現在見られるような3つの湖に分割されてしまいました。北海道の形に似ていると言われるペンケトーは、3つの中では1番小さな湖です。周囲は3.9キロ、一方パンケトーは12.4キロ、阿寒湖は25.9キロです。ペンケトーの水深はおよそ39メートルで、標高は520メートルです。


楽しみ方


パンケトーと同じく、周辺の森林と道は、国や民間により厳重に管理されており、通常一般の人たちだけで行くことはできません。パンケトーよりもさらに奥にある秘湖ですが、双湖台からは全体を眺めることができます。

Lake Penketo


Overview


In the Ainu language, Lake Penketo means “upper swamp.” Located in the eastern foothills of Mt. Oakan, a single outflowing river at the northern end of the lake connects it to Lake Panketo.


Long ago, Lake Penketo, Lake Panketo, and Lake Akan were joined together as one large body of water. However, due to volcanic activity from Mt. Oakan from approximately 10,000 to 6,000 years ago, the original Old Lake Akan was partially filled in and split into the three lakes that exist today. Said to resemble the shape of Hokkaido, Lake Penketo is the smallest of the area’s three lakes. It has a circumference of 3.9 kilometers, compared to Panketo at 12.4 kilometers and Akan at 25.9 kilometers. Lake Penketo is approximately 39 meters deep and is 520 meters above sea level.


Activities


As with Lake Panketo, the forest and road around Penketo is managed by both the government and private organizations. To protect the area’s natural environment, the general public is usually prohibited from going near the lake. However, visitors can view both Lake Panketo and Lake Penketo from the Sokodai Observatory.
