| Dette er et av de mindre kalksteinsbrudd i Bøverbruområdet, Forekomsten har vært prøve besøkt og prøvetatt av Odd Øvering i 2000, men ingen andre detaljer er kjent. |

| Abstract: | |
| Etter anmodning fra kommunene Hamar og Ringsaker har NGU utført en innledende geologisk vurdering av kalksteinsressursene til firmaet Steens kalkbrenneri i Furuberget. I tillegg er det befart en rekke forskjellige kalksteinslokaliteter i kommunene Hamar og Ringsaker i den hensikt å finne alternative uttakssteder for den bruddaktiviteten som foregår i Furuberget. Prosjektet er gjennomført som et samarbeidsprosjekt mellom kommunene Hamar og Ringsaker og NGU. |
