I don’t know of many state or national parks named after a film, the one I do know of is Kodachrome Basin State Park, and I recommend visiting it if you are traveling through the area.  The rock formations and colors are very interesting.

Kodak has (at least at the moment of writing this) a PDF on the film at http://www.kodak.com/global/en/professional/support/techPubs/e55/e55.pdf
