Exposure of Prince Creek Formation along west side of the Colville River, just north of confluence with the Anaktuvuk River

Figure 27. Exposure of Prince Creek Formation along west side of the Colville River, just north of confluence with the Anaktuvuk River. Light-colored, nonmarine sandstones are interbedded with dark-colored coal and carbonaceous mudstone. Note low-angle bedding (gentle dip to right) in sandstone just beneath thickest coal; this is accretionary bedding in a meandering fluvial (point-bar) deposit. Bluff has approximately 300 ft of relief. View to west. Photograph by D.W. Houseknecht.
