Lakes of Europe - Masuria
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

About polish cuisine:
Polish cuisine has evolved over the centuries to become very eclectic due to Poland's history. Polish cuisine shares many similarities with other Central European cuisines, especially German and Austrian as well as Jewish, Belarusian, Ukrainian, Russian, French and Italian culinary traditions. It is rich in meat, especially pork, chicken and beef (depending on the region) and winter vegetables (cabbage in the dish bigos), and spices. It is also characteristic in its use of various kinds of noodles the most notable of which are kluski as well as cereals such as kasha (from the Polish word kasza). Polish cuisine is hearty and uses a lot of cream and eggs. Festive meals such as the meatless Christmas eve dinner (Wigilia) or Easter breakfast could take days to prepare in their entirety.
The main course usually includes a serving of meat, such as roast, chicken, or kotlet schabowy (breaded pork cutlet), vegetables, side dishes and salads, including surówka su?rufka ? shredded root vegetables with lemon and sugar (carrot, celeriac, seared beetroot) or sauerkraut (Polish: kapusta kiszona, pronounced ka?pusta k?i???na). The side dishes are usually potatoes, rice or kasza (cereals). Meals conclude with a dessert such as sernik, makowiec (a poppy seed pastry), or drożdżówka dr???d??ufka yeast pastry, and tea.
