Vogelsberg massif - following the "Vulkanradweg", from Fulda (east), the spots are Grebenhain and today Gedern before pushing west towards Nidda.
We continue our "hunting of basalt" in southern Massif Vogelsberg ... after Grebenhain and St.Boniface Chair, here the Gedern's quarry.
Used by the Counts of Stolberg since the 17th century for the extraction of stone for construction,
this quarry is still partially active. It is reached by a small road, trying to spot the little yellow placard with a black hammer ... much easier with the GPS coordinates: 50° 24'50 - 11'33° 9.

The hole is huge: 500 m. and length of 20 m. depth.
We can detect several superimposed lava interspersed by slag red-brown.
With a little searching, we find spherical bombs mixed in the slag layer, as well as beautiful zeolites in the basanite.
