Thanks for the link to the sign, Kevin. Maybe a sign at the base of the switchbacks would be helpful, just during the fall.

And thanks for the votes for more education and information.

Here's a clip of the sign, originally from Wikimedia Commons.



Of course, I've advocated for a sign on the west side, too, somewhere between the JMT / Portal trail junction and Guitar Lake to warn disoriented hikers from the summit that they are on the wrong trail if they are trying to get to Whitney Portal.
