- Context
- gravel and coarse sand about 10 m above the river, beneath about 20 m of outwash, alluvial sand and aeolian sand
- Associated taxa
- Mammalia: Bison sp
- Additional information
- Carbonate fraction: 1100 +/- 130 BP
- Comments
- DiPm-VP, Castle River: A bison skull and other bones were found in outwash that appeared to represent early retreat of the last major Cordilleran glacier from its maximum advance position. Dates on the organic fractions show good agreement, whereas the carbonate fractions are unreliable.
