Nachos: The google link you provided is down near the Hogback Road junction. Isn't the road closed sign above the big switchback:
Here's the Gmap4 view, it has way more options than Google Maps.
Map of Whitney Portal Road From my recollection, the Road Closed sign is right by the gravel road, which is where I got GPS the coordinates... Unless the Road Closed sign was moved sometime between first of Feb and now.
Thanks for the Gmap4. Definitely way better.
