In the 17th century there were some mines at the Hochstaufen, the best known gallery was the Doktor-Oswald-Gallery, located only 60 m underneath the summit.

After heavy rainfalls earthquakes occur at the Hochstaufen, so there are several seismometers of the Ludwig Maximilian University of Munich around the mountain.
