My great grandfather ran the Wells Fargo in Coulterville, Ca in the 1800's.......he had purchased 640 acres in Greeley Hill....as you come to the top of Ponderosa ....the 640 acres began.....he allowed John Muir to keep his sheep in the pasture that appears as you descend into Greeley Hill..... One of William McCarthy's daughter's, Nellie, rode w/ Muir into the Hetch Hetchy Valley. Nellie McCarthy (married Thomas Elston Jr.) and became Nellie Elston and fought during her life to preserve the valley from being damed....only to see that beautiful valley becoming a lake.. and here we are again considering returning that valley to what it used to be.
