Hochgründeck - Mountain splitting

The Hochgründeck (1,1827 m) is the highest elevation of the greywacke zone in the Alps UNESCO Global Geopark and the ridge shows one of the most important geological-tectonic-geomorphological phenomena. The stretch from the Kiener Haus to the summit of the Hochgründeck runs along a wide crest characterized by a double ridge. This is the indication of a "mountain rift" in the landscape. Mountain splitting with double ridges are characteristic formations in the soft, landslide-prone shales and phyllites of the greywacke zone.

The term "mountain splitting" refers to a two-phase tectonic event in which the rock breaks up or tears open at "relaxation fissures".

This is followed by the sagging of the loosened rock masses under the influence of gravity. Here, the abutment was lost after the Ice Age glacier melted, so the mountain sagged due to pressure relief on both sides, and the double ridge was formed. This process gives the area a "fractured appearance" with temporary water-filled pools and bumpy meadows between the two ridges.

What does a geologist do?

A geologist is someone who studies the earth and its materials. Geologists look closely at rocks, soils and different landscapes to understand how the earth is structured and how it changes. They also help figure out how to protect the environment and where to build safely. They often go outside to take samples and draw maps. Geologists are like explorers who discover the secrets of the earth.

What does a geologist do?

Geologists are researchers who study the earth and its materials. They look closely at rocks, soils and landscapes to understand how the earth is structured and how it has changed over time. They use tools to take samples and create maps, and they often work on conservation projects to protect nature and find out where it is safe to build. Their work is important because it helps us to better understand the Earth and use its resources sustainably.
