Halsåsen kalksteinsfelt ligger nord for tettstedet Rognan på vestsiden av Saltdalsfjorden ca. 2 km fra Rognan. Kalksteinen står opp som benker med nordøstlig strøkretning over hele Halsåsen og videre utover neset som stikker ut i Saltdalsfjorden. Det beste profilet får en i åsens bratte nordvestskråning fra Vikbukta, hvor lagene kan følges fra innmarksjordet nede ved strandkanten og helt til toppen. Hele den 2-3 km lange halvøya som stikker ut i Saltdalsfjorden er i det vesentligste bygget opp av kalksteinsbenker i veksellagning med ulike typer glimmerskifre. Selve åsen går opp i en høyde på ca. 120m og er ca. 0.5 km bred over en lengde på over 1 km. Ref: Bøckman 1956 BA rapp 435
