Mühlsteinbrüche
The Mühlsteinbrüche ("Millstone Quarries", ) south of Jonsdorf in the Zittau Mountains in Saxony are a region of bizarre rock formations, which have been formed by the quarrying of sandstone for millstones and also by weathering processes. They are a popular hiking and climbing area. An educational trail runs through the region which has an area of about 35 hectares. Location and surrounding area The Mühlsteinbrüche are located south of Jonsdorf at a height of 480 to 560 metres. To the southwest they are adjoined by the Jonsdorfer Felsenstadt. About 600 metres to the south is the border with the Czech Republic. Geology The sandstone in the Mühlsteinbrüche region was formed in the geological age of the Middle Turonian and, based on its formation, belongs to the Bohemian Cretaceous Basin. It is characterised by several special features. For example, the sandstone, which was formed by sedimentation, has been breached multiple times by basaltic and phonolitic intrusion (geo ...

Zittau Mountains
The Zittau Mountains (, ; ), formerly also called the Lusatian Ridge (''Lausitzer Kamm''; ''Łužiski česak''), refer to the German part of the Lusatian Mountains that straddle the Saxony, Saxon-Bohemian border in the extreme southeast of the German state of Saxony. Geography Location The Zittau Mountains lie in the extreme south of the district of Görlitz (district), Görlitz in Saxony. A few kilometres north of the range lie a number of settlements; from west to east they are Großschönau (Saxony), Großschönau, Hainewalde, Olbersdorf, Bertsdorf-Hörnitz and Zittau. In the mountains themselves are, again from west to east, the settlements of Waltersdorf (Großschönau), Waltersdorf, Oybin, Jonsdorf and Lückendorf . The highlands are drained by streams that flow roughly north into the Mandau, a western tributary of the Lusatian Neisse. Mountains Among the highest mountains in the range are the following (in order of height in m above Normalnull, NN: [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millstone
Millstones or mill stones are stones used in gristmills, used for triturating, crushing or, more specifically, grinding wheat or other grains. They are sometimes referred to as grindstones or grinding stones. Millstones come in pairs: a stationary base with a convex rim known as the bedstone (or nether millstone) and a concave-rimmed runner stone that rotates. The movement of the runner on top of the bedstone creates a "scissoring" action that grinds grain trapped between the stones. Millstones are constructed so that their shape and configuration help to channel ground flour to the outer edges of the mechanism for collection. The runner stone is supported by a cross-shaped metal piece ( millrind or rynd) fixed to a "mace head" topping the main shaft or spindle leading to the driving mechanism of the mill (wind, water (including tide), or other means). History The origins of an industry Often referred to as the "oldest industry", the use of the millstone is inextr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Bohemia
North Bohemia (, ) is a region in the north of the Czech Republic.

Geography and nature North Bohemia is divided into many landscape areas including the Ore Mountains, the Bohemian Switzerland national park, Mácha’s Country, the Lusatian Mountains and Ještěd Ridge, Frýdlantsko and the Jizera Mountains. It is a popular tourist destination, much of which had been inaccessible until recently. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grinding Mills
A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically, mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind (windmill) or water (watermill). In the modern era, they are usually powered by electricity. The grinding of solid materials occurs through mechanical forces that break up the structure by overcoming the interior bonding forces. After the grinding the state of the solid is changed: the grain size, the grain size disposition and the grain shape. Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material (e.g. mining ore). For instance rock crushing or grinding to produce uniform aggregate size for construction p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature Trail
An educational trail (or sometimes educational path), nature trail or nature walk is a specially developed hiking trail or footpath that runs through the countryside, along which there are marked stations or stops next to points of natural science, natural, technological or cultural interest. These may convey information about, for example, flora and fauna, soil science, geology, mining, ecology or cultural history. Longer trails, that link more widely spaced natural phenomena or structures together, may be referred to as themed trails or paths. In order to give a clearer explanation of the objects located at each station, display boards or other exhibits are usually erected, in keeping with the purpose of the trail. These may include: information boards, photographs and pictures, maps or plans, display cases and models, slides, sound or multimedia devices, facilities to enable experimentation and so on. The routes are regularly maintained. Educational trails with a strong thema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
