Comments
Galt Island Bluff, EaOq-VP: The fauna at this site represents a fairly warm climate. The wood bearing unit is overlain by about 15 m of stream and lake sand, silt, and clay, which is partly varved towards the top, and 15 m of the youngest till in the region. Elsewhere the floodplain silt and clay unit is overlain by two tills. GSC-1442 was made up of wood pieces that were >1 cm long, whereas GSC-1442-2 included some material of this size as well as some smaller pieces. Most of the pieces appeared to be bark. A.M. Stalker comments that sample GSC-1442-2 provides a maximum age for overlying till.
