One sediment sample from a 50 mm diameter core sample taken from the Sibley Site 1, Squaw Bay, Ontario, was collected and submitted for pollen analysis. The core exhibited rhythmic clay with visible dark and light bands. A portion of the core was AMS radiocarbon dated, producing an age of 13,800 ± 60 14C BP (Fred Dean, personal communication, September 6, 2018). The sample was submitted to identify the local vegetation around Lake Superior during the late Pleistocene.

A sediment sample was collected from the Holland Road Pit Site for pollen analysis. An OSL date of 116,000 years was obtained on gray sediments containing gravel that is overlain by beige sand. The till above the gray sediment is probably a weathered version of the black till from the Rosslyn cut-bank that yielded a radiocarbon date of about 42,000 cal BP.
