Long time readers know that I have shot a lot at Mission San Juan Bautista, which is the location of the climax of Alfred Hitchcock's Vertigo. Another moment you may remember from the film is of Jimmy Stewart and Kim Novak at a slice of a redwood with dates in history corresponding with the tree's rings.
I'm not certain if that was filmed at
Henry Cowell State Park, but a very similar, if not the same, slice of a redwood exists at this local treasure.
