| En 50x5m pegmatittgang som ligger et stykke oppe i lia sørøst for Storvatnet ute på Agdenes. Gangen står steilt oppetter en liten berghammer. Det ble av grunneieren her tatt ut omkring 700t kvarts på 1930-tallet (til Meråker bruk?). En bilveg (nå delvis gjengrodd) ble anlagt opp til forekomsten fra nordvest. |
