Comments
DlPm-VP, Todd Creek: This sample may be the same age as the gravels, consequently, it will provide a maximum age for the glaciation that caused these sediments to be deposited. It will put this glaciation in a pre-late Wisconsinan context and demonstrate that a penultimate Laurentide Ice Sheet reached the southern Foothills (a point debated at present).
