- Comments
- HaRe-VP, Ostero Pit: W.H. Mathews comments that the deeper parts of the gravel deposit, from which the mammoth tooth was obtained, are now interpreted as the lower portion of an interglacial succession. Correlative gravels are exposed in cutbanks of Peach River at a similar elevation (ca. 475 m) 0.8 km upstream where they are overlain, in turn, by till and by later glacio-lacustrine beds. At the site of the Ostero pit, however, the silts, clays and younger beds have been eroded away in early post-glacial time by Peace River which left a broad terrace in their place.
