During further ascents to the Summit Cleft I was able to find some beautiful, mainly large fluorite specimens. All of the pieces shown and described here come from the third cavern in the Summit Cleft.

The so-called third cavern is the largest chamber in the Summit Cleft. This is where most, and also the largest, fluorites were found. The ceiling of the chamber was originally crystallized with large fluorite crystals. In exceptional cases the edge length of the crystals could reach over 10 cm. The crystal surfaces of these large fluorites show an intensive parquet structure and the edges are often stepped. Individual pieces are additionally set with a 2nd generation of smaller fluorites. Many of the fluorites had long since fallen from the ceiling and lay on the bottom among the rubble and clay. Underneath the fallen fluorites were several layers of limestone that were crystallized with sharp-edged fluorite cubes up to an edge length of about 3 cm. Most of these specimens were completely covered with calcite. It was only when the calcite was removed that some of the pieces revealed their true beauty. The lowest layer of the soil was interspersed with dolomite and limestone, partly solid and hard, partly sandy and soft. Small, sharp-edged fluorites were also found in this area, but they were unstable due to frost and water and broke during attempts to salvage them. Fluorite was present in large quantities in the rear right area of the 3rd cavern. The large fluorite specimen, which consists of solid fluorite and is crystallized on both sides, comes from this spot. Rock crystals were also found in the third cavern. Primarily as small needle quartz in combination with fluorite and dolomite. Most of these pieces were also destroyed by the frost. Other quartz crystals reached a length of over 10 cm. The crystals were mostly light gray and not beautifully formed. Larger quartz crystals from the Summit Cleft in good quality have only been found sporadically and are a rarity.
