Coal seams up to 23 centimetres in thickness occur interbedded with feldspathic sandstones between 490 and 520 metres in elevation along the banks of the creek. The coal seams occur in one location at closely spaced intervals separated by seams of bone coal. The coal seams are interbedded within the Lower Cretaceous Skeena Group rocks and are part of the Telkwa coal measures.
