| Description |
| Bergarten er ganske lik den som er beskrevet under Mjåland I, men er nok noe mørkere og spalter i tykkere plater enn den. Bruddet er foreløpig lite, men har utvidelsesmuligheter. |
| Location |
| Forekomsten ligger på nordsiden av Mjåvatnet, like opp for vatnet. En skogsvei går fra RV 42 ca 200 m vest for vestre ende av Mjåvatn. Etter vel 500 m på denne veien, vil man se bruddet på norsiden av veien. |
