The Glaswaldsee near the spa town of Bad Rippoldsau-Schapbach in the Central Black Forest in Germany lies in a cirque that is sunk into the steep eastern mountainside of the Lettstädter Höhe. It is part of the nature reserve of the same name that was established in 1960.
Bad Rippoldsau-Schapbach is a municipality in the district of Freudenstadt in Baden-Württemberg in southern Germany.
The Central Black Forest, also called the Middle Black Forest, is a natural or cultural division that generally refers to a region of deeply incised valleys from the Rench valley and southern foothills of the Kniebis in the north to the area of Freiburg im Breisgau and Donaueschingen in the south. Its highest area, which is southeast of the Elz valley, is also part of the High Black Forest.
Germany, officially the Federal Republic of Germany, is a country in Central and Western Europe, lying between the Baltic and North Seas to the north, and the Alps to the south. It borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, France to the southwest, and Luxembourg, Belgium and the Netherlands to the west.

The tarn formed in a cirque that was carved from the bunter sandstone rock out by a glacier during the ice age. Steep banks surround the lake which is up to 11 metres deep and has an area of about 3 hectares. Its diameter varies between 170 and 220 metres. The Glaswaldsee is fed by underground water sources; its surface catchment area, apart from an artificial diversion from the uppermost reaches of the Seebach, only covers about an area of 190 hectares.

A tarn is a mountain lake, pond or pool, formed in a cirque excavated by a glacier. A moraine may form a natural dam below a tarn.
A glacier is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.
An ice age is a long period of reduction in the temperature of the Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth is currently in the Quaternary glaciation, known in popular terminology as the Ice Age. Individual pulses of cold climate are termed "glacial periods", and intermittent warm periods are called "interglacials", with both climatic pulses part of the Quaternary or other periods in Earth's history.
In centuries gone by, the lake was known as the Wilder See ("Wild Lake") (like the Wildsee at Ruhestein and the Wildsee near Kaltenbronn), but its present name is derived from the former manufacture of glass bottles in the neighbouring villages. Today the surface of the Glaswaldsee is raised by a sandstone wall which used to enable the transportation of timber down river as part of the timber rafting industry in the valley of the Wolf.
Wildsee is a small tarn within a cirque in the Black Forest near Baiersbronn, Germany. It is part of the Black Forest National Park and the Wilder See - Hornisgrinde Nature Reserve.
Timber rafting is a log transportation method in which logs are tied together into rafts and drifted or pulled across a water body or down a river. It is arguably the second cheapest method of transportation of timber, next after log driving. Both methods may be referred to as timber floating.
Wolf is a river of Baden-Württemberg, Germany. The historical name of the river is Wolfach. It passes through Bad Rippoldsau-Schapbach and flows into the Kinzig in Wolfach.
The Glaswaldsee is one of the first lakes of the Black Forest to be trigonometrically surveyed and mapped. In 1655 Landgrave Frederick Rudolph of Fürstenberg-Stühlingen directed the Basle priest, Jakob Mentzinger, to prepare a map of his sovereign territory in the Kinzig valley. To illustrate his approach to the national survey, Mentzinger recorded in the lower part of his map an enlarged view of the Glaswaldsee with the calculations made by him.
In trigonometry and geometry, triangulation is the process of determining the location of a point by forming triangles to it from known points.
The Kinzig is a river in southwestern Germany, a right tributary of the Rhine.
