There are a few Building standing and People leave there from Time to Time. Not sure for how long till they get knocked down,as in Owens Valley for Health&Safety Reason every abandoned Building gets erased.
Maybe,If anyone gets the Mining Claim he can keep it running.
Water is rare and Store is far if you leave there and walk.
Im not been there,but was in Bishop and talked to a few who leave there for Times when they cant afford to rent a Home.
