As we sat down on the first summit, I looked south along the ridge, and thought that I saw a slightly higher point. So, we walked along the ridge a few minutes more, crossing two more potential highest summits, before we reached a larger cairn on the next one. After that, the trail descended. My altimeter was not accurate enough to tell which of the four potential summits was the highest, but I think it was the third one, counting from the north.
