Every seven minutes it comes alive with a film exploring the landscape from redwood forests to Southern California deserts, and Sierra to sea. This technique, used repeatedly throughout the museum, adds poetic voice to exhibits. Arguing the contrary, Muir thought it should be preserved. When Pinchot's words are voiced over a speaker, his portrait lights up. At Muir's words, attention is directed through the window where a hologram of actor Lee Stetson as Muir comes to life against a background of redwoods.
Words fly faster as the exchange heats up.
It was one of my favorite parts of the museum. Punch in the numbers on the audio guide, and viewpoints covering both sides are played. There are also the oddities that make any museum fun. Here is a deck of souvenir playing cards of 1898 that show off scenes of California splendors. Most documents are hidden away in shallow drawers in small rooms and alcoves.
