paragraph_text: High levels of precipitation cause the glaciers to descend to permafrost levels in some areas whereas in other, more arid regions, glaciers remain above about the 3,500 m (11,483 ft) level. The 1,817 square kilometres (702 sq mi) of the Alps covered by glaciers in 1876 had shrunk to 1,342 km2 (518 sq mi) by 1973, resulting in decreased river run-off levels. Forty percent of the glaciation in Austria has disappeared since 1850, and 30% of that in Switzerland.

paragraph_text: Arenenberg is an estate with a small chateau, Schloss Arenenberg, in the municipality of Salenstein at the shore of Lake Constance in Thurgau, Switzerland that is famous as the final domicile of Hortense de Beauharnais.

paragraph_text: Several pluvial lakes formed in what is now the southwestern United States during the glaciation of the late Pleistocene. One of these was Lake Bonneville in western Utah, which covered roughly 19,000 square miles (49,000 km). When Lake Bonneville was at its maximum water level, it was 1,000 feet (300 m) higher than the Great Salt Lake.

paragraph_text: Chiemgau impact hypothesis is an obsolete scientific theory that claimed the Tüttensee lake in southern Bavaria, Germany, to be the result of a Holocene meteorite impact. This claim has been refuted by geological research and the finding of a soil horizon of undisturbed peat and sedimentation since the end of the last glaciation period. The lake is in fact one of many kettles under the foothills of the Bavarian alps.

paragraph_text: The last glacial period, popularly known as the Ice Age, was the most recent glacial period, which occurred from c. 110,000 -- c. 11,700 years ago. This most recent glacial period is part of a larger pattern of glacial and interglacial periods known as the Quaternary glaciation (c. 2,588,000 years ago to present). From this point of view, scientists consider this ``ice age ''to be merely the latest glaciation event in a much larger ice age, one that dates back over two million years and is still ongoing.

paragraph_text: The most populous member state is Germany, with an estimated 82.8 million people, and the least populous member state is Malta with 0.4 million. Birth rates in the EU are low with the average woman having 1.6 children. The highest birth - rates are found in Ireland with 16.876 births per thousand people per year and France with 13.013 births per thousand people per year. Germany has the lowest birth rate in Europe with 8.221 births per thousand people per year.

paragraph_text: Lee Lake () is a small lake at the southeast corner of Redcliff Nunatak on the southern flank of Mackay Glacier, in Victoria Land, Antarctica. Redcliff Nunatak projects as a rounded mound of granite above the glacier surface. The ice is piled up on the west side and sweeps around the north and south sides to the lee side, where it is much lower, and where this lake has formed from meltwater. The lake was given this descriptive name by the Western Journey Party, led by Thomas Griffith Taylor, of the British Antarctic Expedition, 1910–13.

paragraph_text: Birth control practices were generally adopted earlier in Europe than in the United States. Knowlton's book was reprinted in 1877 in England by Charles Bradlaugh and Annie Besant, with the goal of challenging Britain's obscenity laws. They were arrested (and later acquitted) but the publicity of their trial contributed to the formation, in 1877, of the Malthusian League -- the world's first birth control advocacy group -- which sought to limit population growth to avoid Thomas Malthus's dire predictions of exponential population growth leading to worldwide poverty and famine. By 1930, similar societies had been established in nearly all European countries, and birth control began to find acceptance in most Western European countries, except Catholic Ireland, Spain, and France. As the birth control societies spread across Europe, so did birth control clinics. The first birth control clinic in the world was established in the Netherlands in 1882, run by the Netherlands' first female physician, Aletta Jacobs. The first birth control clinic in England was established in 1921 by Marie Stopes, in London.

paragraph_text: At 2,501.9 metres above sea level, Säntis is the highest mountain in the Alpstein massif of northeastern Switzerland. It is also the culminating point of the whole Appenzell Alps, between Lake Walen and Lake Constance. Shared by three cantons, the mountain is a highly visible landmark thanks to its exposed northerly position within the Alpstein massif. As a consequence, houses called "Säntisblick" (English: "Säntis view") can be found in regions as far away as the Black Forest in Germany. Säntis is among the most prominent summits in the Alps and the most prominent summit in Europe with an observation deck on the top. The panorama from the summit is spectacular. Six countries can be seen if the weather allows: Switzerland, Germany, Austria, Liechtenstein, France, and Italy.
