Unfortunately, he hasn't been found, and it has been ten days. Sequoia NP posted a news release that they were pulling most searchers off, and changing status to "Limited Continuous Mode". I sure hope they find him or his remains.
He was "at the base" at 3-4 pm. Way past a good turn-around time, and it sounds like the rest of the group left him and went down. Perfect recipe for disaster. So sad.
