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.
The terrain is rather hilly, with connecting lakes, rivers and streams.
The range stretches from eastern Germany along the northern border of the Czech Republic to south-western Poland.
The highest peak of the range is Sněžka (Polish: Śnieżka) in the Krkonoše (Polish: Karkonosze) mountains on the Czech Republic?Poland border, which is 1,603 metres (5,259 ft) in elevation.The current geomorphological unit in the Czech part of the mountain range is Krkonošsko-jesenická subprovincie ("Krkonoše-Jeseníky"). The Krkonoše Mountains (also called the Giant Mountains) have experienced growing tourism for winter sports during the past ten years.
