lpr,
There wasn't any information out on a missing hiker, so I called the Inyo County SAR dispatch. The officer I talked to did not have an incident report for Tuesday, and there were no open incidents currently open.

So I will have to assume that the situation was resolved -- by rangers or by other hikers on the trail. That is usually the case, that alarms are raised, but the missing person finds their way out with the help of others on the trail.

That is one of the good things about the Main Mt Whitney Trail, that there are so many hikers using the trail, that someone in need of help can usually get it from the other hikers.
