- Comments
- RbJu-VP: Periotic bones were collected in situ from both sides of a bowhead skull 90% exposed in colluvium on the side of a stream cut. The colluvium consists of well rounded gravel covering a 20 metre high face. The incised sediment appears to be gravel throughout but is nowhere freshly exposed. The top of the section is in raised beach gravel but this is not likely more than a metre or two thick. The skull could have fallen down from the beach at the top of the section at 34 metres above sea level or could be outcropping at its original position in the mid-section sediment. In either case, the minimum relative sea level to which it relates is 34 metres, assuming that the bone is of postglacial age.
