Mellom disse 2 koordinatsett er det anlagt 6 skjerp/synker, 3 i hver ende. Det er ingen vits i å beskrive alle disse skjerp/synker, her skal bare meddeles noen generelle forhold. En gårdsvei som tar av fra hovedveien til Langevåg går rett forbi de tre første skjerp/synker. Litt lenger mot sydvest blir gårdsveien til en sti, og ved enden av denne ligger de øvrige 3 skjerp/synker (ved det ytterste huset). I den nordøstlige enden er det 2-2.5 meter kvarts, i den sydvestlige enden er det høyst 1 m kvarts. Den kvartsmineraliserte delen av løsmassen ligner løsmassen fra "gullgruveområdet", med den vanlige hvite kvartsen og den hvite til rødlige karbonaten. Sulfider ses nesten ikke. Undertegnede finner mineraliseringen uinteressant, da her nesten ikke finnes sulfider. Mineraliseringen er ikke omtalt i litteraturen
