Here is a Google map view I tagged up to make it a bit easier to envision. I hope.
The blue squares that represent campsites are not exact campsite locations, just more of an idea of how the sites are arrayed in each campground.
"Ravine" campground labelled on the map is the "secret" one most talked about here that I camped in.
Excellent work, gmaki! So very helpful. If you don't mind...
Could you add to the map:
Whitney Portal Store
Mt Whitney Trailhead
An arrow on the left end of the green road with something like "From/To Lone Pine")
Is your right-most red line a walking trail or ?
