- Comments
- DfRu-13, Montague Harbour: This site is a stratified shell midden with three cultural horizons numbered from bottom to top: I. Locarno Beach phase; II. Marpole phase; III. Developed Coast Salish. Mitchell commented that as Montague Harbour I materials seemed to align closely with another Locarno Beach phase site, Pender Canal (DeRt-2) dated 2200 +/- 120 BP (M-1515), it was originally thought that samples from DfRu-13 would be 2000 to 2500 years old. Present dates must alter our opinion of Locarno Beach phase sites, but they do not mean a substantial realignment in thinking. Three of the seven samples submitted to the National Museum were never forwarded to a radiocarbon laboratory.
