Skjerpet ligger på nordsida av Gyadalen, i overkant av en ur i brattskråningen på sørsida av Almefjellet i en høyde av 475 moh. Et opptil 3 m langt og 2 m bredt innslag med retning 325° er slått inn i den skrånende fjellsida og taket er 0,5-1 m langt. Det ligger i en rustsone som fortsetter med ca. retning N-S videre oppover fjellsida. Dominerende bergart i området er middelskornet, lys granittisk gneis med dels gradvis overgang til 10-40 cm brede pegmatittiske linser. De er noe uregelmessige, men hovedsakelig orientert nord-sør med steilt fall mot vest. Pegmatittene fører noe amazonitt og granat. Øst for skjerpet er gneisen dels hornblende- og biotitt-førende og har foliasjon 158°/80°. Magnetkis og mindre mengder kobberkis og molybdenglans opptrer som massive aggregater (prøve .01), årenett eller disseminert i pegmatitt (.02) i skjerpet. I den granittiske gneisen finnes mindre mengder magnetkis og kobberkis disseminert og i korte strenger/stikk (.03).
