Skjerpet ligger i brattskråning tett ved oppkjøring til et nyere bolighus nordøst for Heddal kirke. Det skal være skjerpet før 1865. Det følger et naturlig trinn i terrenget og er omtrent 5 m langt med en opptil 2,5 m høy, naturlig skjæring. Det er anlagt langs en mørk, biotitt-rik sone i en fint båndet kvarts-feltspat rik gneis som trolig representerer et metasediment. Sona er 20-30 cm mektig og fører svak disseminasjon av kobberglans+bornitt?. Forekomsten er ubetydelig. |
