Where: British Columbia, Canada (48.5° N, 123.3° W: paleocoordinates 48.5° N, 123.3° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tarantian (0.1 - 0.0 Ma)

• "The deposit is overlain by about 180 feet of clay, sand, and gravel, the Cordova sands and gravels and Maywood clays constituting the Puyallup interglacial deposits, with Vashon drift above. Of the Puyallup deposits the Maywood clays are the older, and in them is the lignite bed with marine shells in the overlying clay and finely stratified whitish clay underlying it." Puyallup interglacial spans MIS 49-29, from about 1.5-1 Ma, but this section is actually late Pleistocene based on radiocarbon dates c. 22.5 ka BP.

Environment/lithology: mire or swamp; poorly lithified lignite
