SaltyDog:
"I just called this number and was astonished to be told that the family had NOT reported this to Inyo Sherrif or anyone else. I did that and urged the family to call the number I gave them for ICSO, which is posted at the site."
If you had not contacted the family there may have been a significantly worse outcome.
But that is what this forum is all about.
I don't want to take too much credit here: the hiker's friends on the Inyo side had initiated SAR, but the family were not completely informed, apparently. I was just makin' sure.
