7. Spring Week 2014: Short documentation Sources

The photographs in the Dürrenstein wilderness area in 2014 were mainly taken in the Rothwald jungle or in the adjoining peripheral areas. In the valley bottom partly very flat, then steeper rising jungle areas against the back slope stand on Dachsteinkalk or a special facies of this carbonate large unit, the Bärwiesschichten. Here, slightly alternating dolomitic with pure calcareous, relatively thin benches, so that there are always karst springs and streams, which otherwise rarely occurs in the Dachsteinkalk above the pre-flood. In the edge of the Gesäuse National Park, the Mühlbachgraben was visited on the northern slope of the Buchstein Massif. This area is mainly located in the middle to lower Triassic of the Northeastern Limestone Alps. While the crowning rock walls and kare of the Buchstein Massif are built from the Dachsteinkalk and main dolomite and are waterless throughout, some smaller spring horizons emerge on the Raible Band. The main water turnover in the Mühlbachgraben, however, is based on the permoskythian limestone base (Werfen sandstones, lime marl and quartzite, Haselgebirge). Here, a very wide source horizon has emerged from karst waters of the Buchstein massif at the congestion layers. Morphologically, this zone confronts us as a pre-alpine landscape at the foot of the Buchsteinstock.
