you might try calling the city of Bishop and ask them if they’ve ever heard of their famous Namesake the Bishop Mill.
The town of Bishop was named after Bishop Creek, which was, in turn, named after Samuel Bishop.....a rancher. Not a miner, and nothing to do with a mill.
Also, the current Bishop Mill was built on undeveloped BLM land in the early 1980's....illegally, because they didn't disclose they were disturbing more than 5 acres. Great start, right?
Maybe quit making shit up?
