Nedlagt kalksteinsbrudd delvis brukt som fyllplass. Bruddet er 250x70 meter og ligger kun noen få hundre meter fra bebyggelsen i Mjøndalen. Kalken er ganske sterkt derformert og fosslirik. Bebyggelse gjør at ingen av forkomstene i Mjøndalområdet er av interesse idag. Kjemisk analyse viser at at kalken inneholder 50.23 og 2.55 % syreløslig CaO og MgO. Uløst rest er på 9.18%
