Well, Lafayette has a hut below it. From this article, it does seem to be an issue, "We're seeing human waste along trails,” Benna says.
"Trouble on the Trails"
The other thing is that we really don't want people stepping off trail on the ridge and destroying the diapensia. It is less of an issue when hikers can step into the woods, although it does violate Leave No Trace, since, if we're being honest, most folks (I suspect) are not digging catholes.
I also get the impression that the hut croos assist or solely conduct a fair number of rescues.
