Tony Immoos sent me links to a nice map he created by using a handy map tool at HeyWhatsThat.com (aka HWT)

See it yourself: Half Dome on HWT.

Tony's flickr page is here:  Half Dome Viewing Area

Here's his map created using the "Visibility Cloak" feature on the HWT.

Here's how Tony created the big map:

So what I did was zoom back in a bit to get some detail, then I made a screen capture of the map, moved it and made another, and another and another.... I then pieced them together in Paint Shop Pro like a puzzle and came up with a 5000x4000 pixel map showing all the places you could see HD from.
Thank you, Tony!!!

I did not know about HeyWhatsThat.com until now.  It's a great site -- should be handy for generating some nice profiles and maps.
