The Erlspitze Group ( German : Erlspitzgruppe ), also called the Seefeld Group, is the southwesternmost side range of the Austrian part of the Karwendel mountains in the Alps . It forms a horseshoe-shaped highland around the valley of Eppzirler Tal and is joined in the south to the Nordkette by the Erl Saddle ( Erlsattel ) near Solsteinhaus . It is bounded in the west by the Seefeld Basin, in the east by the valleys of the Gleirschtal and the Großes Kristental; its forested northern foothills reach as far as Scharnitz .
4-646: Unlike the four main ranges of the Karwendel, the Erlspitze Group is made of Main Dolomite . Typical of this rock are bizarre weathering forms, like towers , pinnacles and sharply formed arêtes as well as rock arches and caves as a consequence of the rapid erosion of individual rock strata . Its valley bases are Hochzirl , Reith , Seefeld and Scharnitz , all of which are on the Innsbruck - Mittenwald section of
8-867: Is a lithostratigraphic unit in the Alps of Europe. Formation was defined by K.W. Gümbel in 1857. Middle to Late Triassic sedimentary record in the Alpine realm is characterized by presence of various masses of dolomitic rock formations. In the Northern Calcareous Alps the dolomitic mass of Ladinian - Norian age is divided by the Carnian sandstones and shales of Lunz Formation to the Ladinian - Carnian Wetterstein Dolomite and Norian Main Dolomite. The Main Dolomite reaches higher thickness than underlying dolomites in Alps, therefore it
12-541: Is considered as more important "Main". The formation is found in: It is primarily made of dolomite , ranging from 0 to 2,200 metres (0 to 7,218 ft) in thickness. Main Dolomite is represented by the medium bedded dolomitic layers often with characteristic stromatolitic lamination. The formation was deposited in shallow lagoons during the Late Carnian and Early Norian ages of the Late Triassic Epoch in
16-960: The Mittenwald Railway . Two alpine club huts act as bases for tours in the area of the Erlspitze Group: in the west is the Nördlinger Hut and, in the south, is the Solsteinhaus . In the northern part of the Erlspitze Group are two huts open in summer: the Oberbrunnalm and, in the Eppzirler Tal, the Eppzirler Alm .
