The Michaelstein , formerly also Michaelsstein or St. Michaelsstein , on a current city map also just Michlstein , is a boulder in the river bed of the Isar east of Baierbrunn in the district of Munich , below (north) the larger and better known Georgenstein .
geography
Michaelstein is located at river kilometer 163.0 in the Isartal landscape protection area on the western edge of the community-free area Grünwalder Forst ( district Grünwalder Forst, district part 2) east of Baierbrunn, a good 10 meters from the east bank of the river, and around 160 meters downstream from the Georgenstein, together with some smaller boulders. The municipality boundary is formed here by the western bank of the river.
This section of the Isar, which already belongs to the lower reaches of the river, has some nameless gravel islands immediately to the west of the rocks. All gravel islands between river kilometer 164.6 (confluence of the free Isar and Isar canal north of the Mühltal power station) and river kilometer 162.5 (Baierbrunn weir) may not be entered during the breeding season.
Although surrounded by water, boulders like the Michaelstein, like other stones, are not considered islands due to their formation . The Michaelstein is 12 meters long and seven meters wide, and rises around two meters above the water level of the river, which in turn lies at 544 meters above sea level. The boulder is much flatter than the Georgenstein rising steeply from the river. Just like on the neighboring gravel islands, driftwood regularly collects here during floods .
The Michaelstein has the same history as the Georgenstein. Geologically, it is therefore also a block of ballast from the Old Pleistocene , which was torn from the eastern slope of the Isar and slipped into the river bed on the underlying Tertiary layers from the Miocene . It consists of a conglomerate rock called Nagelfluh in southern Bavaria . In contrast to the Georgenstein, the Michaelstein is not recorded in the geotope register of the Bavarian State Office for the Environment.
The old Römerschanze von Grünwald towers high above the Michaelstein and the Georgenstein. It is 615.8 meters above sea level and is around 70 meters above the river bed.
history
The rapids at the height of the Michaelstein and the Georgenstein used to be a problem for the raftsmen . The Topo-Geographical-Statistical Lexicon of the Kingdom of Bavaria from 1831 says: ... at the Michaelsstein, Georgstein and Grünwald are dangerous places for the raft trip; often the river rushes violently against the rocks here, so that the rafts fail.
The creation of a dam to the Georgenstein, which directs the current to the left around the rock, also defused the Michaelstein downstream.
From around the 12th century to the beginning of the 20th century, rafting was used to transport goods, especially wood.
Before the Michaelstein got its current name in the early 19th century, it was known as "Kleiner Heiner", while the later Georgenstein was called "Großer Heiner". “Little Heiner”, on the other hand, was Michaelstein's earlier name.
Today the raft trips on the Isar from Wolfratshausen to Munich have a folk festival-like entertainment character.
