Wapiti Lake (Triassic of Canada)

Where: British Columbia, Canada (54.5° N, 121.7° W: paleocoordinates 25.7° N, 34.5° W)

• coordinate stated in text

• hand sample-level geographic resolution

When: Vega-Phroso Siltstone Member (Sulphur Mountain Formation), Smithian (251.3 - 247.2 Ma)

• member-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; brown siltstone

• "This member is interpreted as having been deposited in a restricted, relatively

•deep-water environment, although some evidence indicates that at times deposition may have been above active wave base (Gibson 1975)"

• The Vega-Phoroso Member of the Sulphur Mountain Formation (Gibson 1972, 1975) consists of Baggy weathering shale at its base that intertongues with, and is overlain by, a sequence of rusty brown siltstones."
