To me it sounds like SAR talk. Extraction happens too.

Dude is a typical Yosemite tourist - yesterday, as I tried to have infinite patience with everyone in slick soled shoes s-l-o-w-l-y descending the wet steps of the Mist Trail, I must have looked like I belonged there, as I was asked multiple times where the falls were ("well, did you notice you are wet? yes? you're almost there....") On the second bridge (along the river between Nevada and Vernal): "Where is the JMT? Do you know the way to Nevada Falls?"

Not many of them understand where they are... Most of them make it back okay. Glad he was among them, even if he didn't led everyone on a waterfall hunt.... He's lucky.
