I agree about wanting to see more pictures, not just descriptions and maps of the facilities.

Thanks for the link to the galleries here. Definitely helpful, though it would be nice to have them filed under galleries of the particular parks...like was done with Big Bend and Padre Island National Seashore .

I'll have to check out that book.

Another option that may be helpful is one of the satellite imaging sites like maps.google.com or the Google Earth program. terraserver.microsoft.com isn't as good for satellite images, but one advantage it does have is that once you do find a place, you can easily switch over to a topo map as well...so those sources can help you even a little more than hand-shot pictures.
