Basaltkrater Blauer Stein, Natural monument and former quarry in Windeck, Germany.
Basaltkrater Blauer Stein is a former quarry site displaying distinctive angular basalt columns that emerged from volcanic cooling deep underground. These hexagonal stone formations were later exposed when miners extracted basalt from the landscape, leaving behind this geological display.
Volcanic activity during the Miocene period created the basalt deposits that now define this site. Extraction by mining operations in the early 1900s exposed the underground cooling patterns and left the terrain as it appears today.
The Citizens and Beautification Association of Leuscheider Land transformed the former quarry into a destination for geological exploration during the 1970s.
A marked circular route guides visitors through the site with manageable walking terrain suitable for most people. Parking is readily available near the trailhead, making access straightforward and convenient.
The magma froze within a funnel-shaped vent, creating angular basalt columns that now protrude from the ground as geological structures.
