På dette sted har det kun vært et ubetydelig uttak av kalk. Hele odden består av kalkstein i flere hundre meters bredde. Kalken er urein og sterkt skifrig og svært oppblandet med silikater. Den er grålig og finkornet. Enkelte tynne horisonter med rein kalk finnes. Området er idag en feriekoloni for psykisk utviklingshemmede. Kjemiske analyser viser at kalken har et CaO innhold fra 43- 49% og et MgO fra 1.19-4.13%. Dette viser at kalken har et kalkspatinnhold som varierer fra 68-85%. Det vil si en ganske urein kalkstein.
