Yorkville is located 7.5 miles southwest of Hopland. It is on Route 128 and you pass through it en route from Boonville to Hopland. The original townsite was about 3 miles northwest of the present site. The Yorkville post office opened in 1868 and moved to the new site with the town in 1937. “The Late Pomo or Ma-cu-maks of the present day Yorkville area spoke the central Pomo language.”
So now you know where Yorkville is to be found.
I was thumbing through this book …
… when I came across the following page. The Native American Pomo are widely thought to have no written language and to my knowledge nothing has been found in the way of rock or cave drawings/markings. So, I was dumbfounded to find, quite by accident, that Pomo and/or their predecessors did indeed leave “writings.”
