| Forekomsten ligger øst for gården Brennatrøa. Den har en mektighet på 8-15 m og en utstrekning på ca. 1 km. Kalksteinen er grovkrystallinsk og hvit. Det har vært drift på forekomsten, men i dag ligger den midt i bebygd område og det er derfor utelukket med ny drift. Kjemisk analyse viser at kalken er en kalkstein med 53,72% og 0,48% syreløslig CaO og MgO |
