- Comments
- DlLh-VP1: Comment (E. Nielsen): Natural river cut where Truro Creek joins Assiniboine River in west end of Winnipeg. Sample was excavated from dry compact silt. No mold or plant growth. Date of sample will help establish timing of occupation of Assiniboine River. Estimated age about 2 ka BP. Rannie et al. suggest the river drained into Lake Manitoba between 7.5 and 3.0 ka BP. Previous date of 7500 +/- 80 (GSC-4839) suggests river occupied the present course in early Holocene.
