Skjerpet ligger sør for Fiskumelva på en kolle som heter Tamburhaugen. En traktorveg går like ved. Det består av en trekantet grop 3x3 m i omriss og inntil 3 m dyp. Nord i skjerpet står en vertikal kvartsgang med kam-kvartsstruktur. Den er 30 cm mektig og er ellers noe båndet og inneholder noe kullblende i form av fragmenter. Litt malakitt og azuritt viser at det er litt kobber, ellers er det ikke synlige sulfidmineraler. Sidebergart er kvarts-feltspat gneiss.
