100 mill years ago there were a rich volcano activity in a 20 * 20
km area north of Höör. Today the craters of the volcanos
are still visible in the landscape as soft round hills covered with
trees.
This series of caches will show you a few of the volcanos.
At Lunden it should be possible to find basaltic columns from
the crater, but we have not been able to locate them. Please tell
us if you find them.
