- MlVl-14, Old Crow River Locality REM78-1: A large mammal bone with four dates (MlVl-14: 24) provides an important geochronological control for the top of Unit 2b. This bone was recovered from an ice-wedge pseudomorph just below the glaciolacustrine clay (Unit 3). The dated bison tibia is from Disconformity A and exhibits possible butchering marks.
