Archive Wray mentions the new school while winding yarn on some sort of stick. The stick is a drop spindle, a 10,000 year old tech for twisting loose fibers into thread or yarn. The Fort Langley National Historic Site, where these scenes were filmed, has a resident spinner/weaver who regularly demonstrates both drop spindles and spinning wheels.
In this episode, all the scenes with wood houses, log cabins and palisade fences were filmed at Fort Langley National Historic Site near Vancouver. This site was also used for a few Stargate SG-1 (1997) episodes.
