Where: Washington (47.7° N, 122.4° W: paleocoordinates 47.7° N, 122.4° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Olympia beds Formation, Late/Upper Pleistocene (0.1 - 0.0 Ma)

• 14,760 +/- 95 C14 age, calibrated age range 17,761-18,430 (1 s.d.), median probability 17,959 calibrated YBP. Correlative to Quadra Sand (Port Moody Interstade) and MIS 2.

• bed-level stratigraphic resolution

Environment/lithology: fine channel fill; unlithified, fine-grained sandstone

Size classes: macrofossils, mesofossils

Preservation: original chitin

Collected by Allan Ashworth

Collection methods: bulk, sieve,

• The sediments were disaggregated by wet sieving and the fraction remaining on the 300 micron mesh sieve was soaked in lamp oil (kerosene, paraffin oil) and the chitin floated from the mostly organic fraction using water.
