When looking for information about Spuzzum, I ran across this photo of the sign for the Scuzzy Creek Forest Service Road in British Columbia.
Scuzzy Creek is a creek in British Columbia that joins the Fraser River just upstream of Hell’s Gate. From some extensive Googling, and from its general location, it appears that Scuzzy Creek was panned for gold during the Fraser Canyon Gold Rush.
I have found two very different versions of the origins of the name Scuzzy Creek. This web page says that Scuzzy, (or the word it may come from, Scaucy – also the name of the Indian Reserve right beside Scuzzy Creek), means jump or jumping, so Scuzzy Creek is probably named after its waterfalls. However, it may also be that Scuzzy Creek was named after the sternwheeler Skuzzy, the first steamwheeler to successfully navigate through Hells Gate.
