Ore Mountains

The Ore Mountains (Czech: Krušné hory^{? /i}) are low mountain ranges in Saxony and Bohemia. Just north of the ridge line runs the German-Czech border. The highest elevations are the Klínovec (1244 m above sea level) and the Fichtelberg (1215 m above sea level).

The nature of the Erzgebirge has been intensively shaped by human intervention since the first wave of settlement in the Middle Ages and has given rise to a diverse cultural landscape. In particular, mining with dumps, dams, ditches and pits also directly shaped the landscape and the habitats of plants and animals in many places. A selection of historically largely original preserved technical monuments as well as individual monuments and material entities related to mining (17 on the Saxon side and five on the Czech side) have been included in the UNESCO World Heritage List as the Mining Region Ore Mountains since 2019.

The higher altitudes from about 500 m above sea level on the German side belong to the Erzgebirge/Vogtland Nature Park - the largest of its kind in Germany with a length of 120 km. The eastern Ore Mountains are protected as the Osterzgebirge landscape conservation area. Other smaller areas on the German and Czech sides are under state protection as nature reserves and natural monuments. There are also several larger raised bogs in the ridges, fed only by rainwater. The Ore Mountains are a popular hiking area and there are winter sports areas in the high altitudes.

Natural area classification

There is no valid natural area classification for the entire Ore Mountains, as the definition and characterization of natural areas is carried out by the states and federal provinces, so that the Ore Mountains have different classifications for the Saxon and Czech parts. However, the western and eastern boundaries are largely aligned. The total area is about 5262 km².

Saxon Ore Mountains

The most detailed natural spatial classification of Saxony, and thus also of the Saxon Ore Mountains, was drawn up between 1965 and 2007 by the "Naturhaushalt und Gebietscharakter" (Nature balance and area character) working group of the Saxon Academy of Sciences in Leipzig. This subdivides Saxony into geochores, which are called micro-, meso- and macrogeochores with increasing aggregation of uniform areas. An independent natural area designation "Erzgebirge" is not held out there, but the macrogeochores Westerzgebirge, Mittleres Erzgebirge and Osterzgebirge. The boundaries between these are formed by the slopes of the deeply incised rivers Schwarzwasser / Zwickauer Mulde (between the Western and Middle Ore Mountains) and the Flöha (between the Middle and Eastern Ore Mountains). Together with the natural regions Vogtland, Elstergebirge, Sächsische Schweiz, Oberlausitzer Bergland and Zittauer Gebirge these three form the natural region Sächsisches Bergland und Mittelgebirge. The adjacent natural regions are from west to east: Vogtland, Erzgebirgsbecken, Mulde-Lösshügelland, Östliches Erzgebirgsvorland and Sächsische Schweiz. The three Erzgebirge macrogeochores are divided into a total of 51 mesogeochores and 318 microgeochores. The total area of the Saxon Ore Mountains is 3655.45 km².

The Saxon State Office for the Environment, Agriculture and Geology chooses a different aggregation of microgeochores for the preparation of land use plans and divides the Ore Mountains into six landscapes by introducing an altitudinal grading in each case.

Landscape	Area (km²)
Lower Westerzgebirge	276,12
Upper Westerzgebirge	509,10
Lower Middle Ore Mountains	1038,57
Upper Middle Ore Mountains	341,80
Lower Osterzgebirge	1256,71
Upper Osterzgebirge	236,58

In the older natural classification of Germany of the former Federal Institute for Regional Geography, which was published between 1953 and 1962 and considered the whole of Germany as well as neighbouring areas, the Ore Mountains represent the main unit group 42 with five subdivisions. However, no mapping was done, only a description of the natural areas. The border between upper and lower Westerzgebirge on the one hand and upper and lower Osterzgebirge on the other hand was also formed by the river Flöha, so that in this subdivision the border of the Westerzgebirge was clearly further east. This subdivision was simplified for the evaluation of protection purposes (FFH areas, nature reserves) by the Federal Agency for Nature Conservation in 1994. The subdivisions were merged, but the Erzgebirge remained a main unit group under the key D16 with practically unchanged boundaries. The Federal Agency for Nature Conservation has further subdivided these and issues corresponding fact sheets for the individual areas.

Krušné hory

The Geomorphological Classification of the Czech Republic divides the Czech territory into a total of ten hierarchical levels. This classification is based less on landscape and natural aspects and more on geomorphology, i.e. relief. The unit corresponding to the Bohemian Ore Mountains is called Krušné hory, as is the Czech name for the entire Ore Mountains. This main unit forms the 6th level of the classification with 92 others, which usually include natural landscapes. Superordinate are:

Hercinský systém → Hercynská pohoří ("Heartynids") → Česká vysočina (Bohemian Mass) → Šumavská subprovinice → Krušnohorská subprovincie → Krušnohorská hornatina.

Krusne hory borders from east to west on the following main geomorphological units: Děčínská vrchovina (Bohemian Switzerland), Mostecká pánev (North Bohemian Basin), Doupovské hory (Doupov Mountains), Sokolovská pánev (Falkenau Basin) and Chebská pánev (Cheb Basin).

The subordinate units are:

Topographical description

Area, neighbouring landscapes and boundaries

The Ore Mountains are about 150 km long in (south-)west-(north-)east direction and 40 km wide on average. From a geomorphological point of view it is divided into Western, Central and Eastern Ore Mountains, separated by the valleys of Schwarzwasser and Zwickauer Mulde resp. Flöha ("Flöhalinie"), whereas the division of the western part along the Schwarzwasser is more recent. The Osterzgebirge is mainly characterized by extensive, slowly rising plateaus, which are smaller in the more indented and higher reaching central and western part and are also intersected by more frequently changing direction valleys. The ridge of the mountain itself forms, in all three segments, a succession of plateaus and individual mountains.

To the east are the Elbe Sandstone Mountains, to the west the Elster Mountains and other Saxon parts of the Vogtland. South (east) of the Central and Eastern Ore Mountains lies the North Bohemian Basin, immediately east of which is the Bohemian Central Upland, separated from the Eastern Ore Mountains by narrow foothills of the above-mentioned basin. South (east) of the Westerzgebirge lie the Falkenau Basin, the Egergraben and the Duppau Mountains. To the north the border is blurred, because the Erzgebirge, as a typical representative of the Pultschollengebirge, slopes very flat.

The transition zone between the western and central Erzgebirge mountains and the loess hill country to the north between Zwickau and Chemnitz is known as the Erzgebirge basin, while the area north of the Osterzgebirge mountains is known as the Erzgebirge foreland. The Erzgebirge foreland between Freital and Pirna is called the Dresden Erzgebirge foreland or the Bannewitz-Possendorf-Burkhardswalder plateau. Geologically, the Ore Mountains extend to the city limits of Dresden with the Windberg near Freital and the Karsdorf Fault. The notch valleys of the Osterzgebirge break through this fault and the valley shoulder of the Elbe basin.

Within the low mountain range threshold, the Ore Mountains belong on the one hand to the mountain range called Bohemian Mass, which also consists of the Upper Palatinate Forest, Bohemian Forest, Bavarian Forest, Lusatian Mountains, Jizera Mountains, Giant Mountains and the inner Bohemian Mountains. Likewise, with the Upper Palatinate Forest, Bohemian Forest, Bavarian Forest, Fichtelgebirge, Franconian Forest, Thuringian Slate Mountains and Thuringian Forest, it forms a ypsilon-shaped mountain complex which, although it does not have its own name, is to be assessed climatically quite uniformly.

Following the tradition of the cultural areas, Zwickau historically still belongs to the Erzgebirge, Chemnitz lies in an analogous way historically just outside and Freiberg is again included. The presumed border of the Erzgebirge runs further southwest of Dresden towards the Elbe Sandstone Mountains. The main character, i.e. flat plateaus rising to the ridge and incisive valleys, continues to the southern edge of the Elbe basin. North of the Erzgebirge, the landscape gradually changes into the Saxon Loess Gefilde. The cultural transition to the Elbe Sandstone Mountains is very blurred at the height of the Müglitz and Gottleuba valleys.

Remarkable surveys

The highest mountain in the Ore Mountains is Klínovec (Keilberg) at 1,244 metres in the Bohemian part of the mountains. The highest elevation on the German side and at the same time the highest mountain in Saxony is the 1,215-meter-high Fichtelberg. In the Ore Mountains there are about thirty elevations with a height of more than 1,000 meters above sea level, but not all of them are prominent mountains. Most are found around the Keilberg and the Fichtelberg. About a third of them are on the Saxon side.
