| Description |
| Bergarten er en steiltstående sandsteint med lys brunlig farge. Den synes å ha god kløv, og spalter i relativt tynne plater (3-5 cm). Ingen produksjon var foreløpig kommet i gang, men bergarten burde egne seg godt til heller. Driftsmessig er forholdene gunstige,- godt skjermet og god avstand til bebyggelse. |
| Location |
| Forekomsten ligger ca. 300 m NNØ for gården Håland på Øynaheia. Håland ligger på veien mellom Mjåvatn og Grimstad, ca. 2 km SSØ for kryss mot Herefoss. |
