This evidence at Kosapsom tells us that a house-pit was constructed during the Gulf Of Georgia time period. The buried housefloor in the six F and G units was anticipated and later confirmed from C14 dates to be from the Gulf of Georgia Cultural Type. The problem at Kosapsom is that the radiocarbon dates taken from Locarno Beach strata do not fall within the standard range for Locarno Beach times. This means that more excavations are needed at this site in order to solve this problem. Without meticulous digging and note taking, information obtained from Kosapsom would be lost forever.
Excavations are unfortunately destructive to archaeological sites.
The idea behind excavating is to minimize the amount of destruction.
