| Skjerpet ligger 20 m vest for veien opp til Bergstul seter, i et mindre dalsøkk 200 m NØ for Haugen seter. Det er vannfylt med sidevegger 5x2 m, lengste side har retning 60º. I NØ-veggen sees middelskornet, rødlig grå felsisk metavulkanitt, mens metagabbro finnes i en mindre blotning SV for skjerpet. En kvartsgang er sporadisk synlig langs SV-veggen av skjerpet, men det er ikke mulig å bestemme verken retning eller mektighet til denne. På tippen sees få blokker av kvarts med pyritt, blyglans og mindre mengder kobberkis. Sulfidmineraliseringene er også anrika langs kontakten mot sidesteinen. Grønnbrun turmalin (?) finnes også i kvartsen. Forekomsten er ubetydelig. |
