Wonderful polish lakes
Masuria and the Masurian Lake District are known in Polish as Kraina Tysiąca Jezior and in German as Land der Tausend Seen, meaning "land of a thousand lakes." These lakes were ground out of the land by glaciers during the Pleistocene ice age around 14,000 - 15,000 years ago, when ice covered northeastern Europe. From that period originates the horn of a reindeer found in the vicinity of Giżycko.96 By 10,000 BC this ice started to melt. Great geological changes took place and even in the last 500 years the maps showing the lagoons and peninsulas on the Baltic Sea have greatly altered in appearance. More than in other parts of northern Poland, such as from Pomerania (from the River Oder to the River Vistula), this continuous stretch of lakes is popular among tourists. The terrain is rather hilly, with connecting lakes, rivers and streams. Forests account for about 30% of the area.9798 The northern part of Masuria is covered mostly by the broadleaved forest, while the southern part is dominated by pine and mixed forests
