it would have been slash and burn agriculture to start, so there is the likelyhood of fiding artifacts assosiated with charcoal and other evidence, as these people were probably hunter/farmer/gatherers a particular tool kit is going to be definitive, hunting ,fishing and birding points, wood and hide tools, plus agricultural tools, picks, shovles, and hoes,and cythe blades that show up in early agriculture elsewhere with layers of identifiable pitholiths still adhering to them......possibly allready found, but missidentified. also living at the 45'th parallel does require substansial winter prep and strurdy housing as it's still frozen solid for months every winter
