A quarry with very sporadic use. No blasting has taken place in recent times (report 2024). A few piles of gravel in one end of the quarry area indicate that aggregates are still being transported to wathever nearby project that needs a few loads.

From a mineralogical point of view the quarry is uninteresting. No sign of collectable minerals have been observed.

However, from a geological/petrological point of view the quarry represents interesting study material.

A variety of supposedly meta-sediments has been intruded by several pegmatite dikes. The meta-sediments are steeply dipping.

An intense orange-red colored rock, comprising mainly feldspar, forms pegmatite-like dikes. These are easily acceptable in the middle of the quarry at the ground-level.
