| Et lite skjerp med opptil 3 m høye vegger, ligger mellom skogsbilveien og bekken. Flere subparallelle kvartsganger og -årer med orientering omkring 175°/40° finnes langs skifrigheten i vertsbergarten som er kraftig forvitra. Denne sona er ca. 2 m mektig og har delvis et breksjert utseende. Pyritt og få korn av blyglans finnes disseminert i kvartsårene. |

| Skjerpet består av en kort stollinnhugg (< 1 m) i en svært finkornet kvartsittisk bergart med kvartsårer og svak disseminasjon av pyritt, på sørsida av et Ø-V orientert søkk. Kvartsårene er omkring 1 cm brede. På nordsida av søkket finnes en middelskornet, udeformert meatgabbro. |
