That failed attempt captures something essential about Florissant Fossil Beds: this place resists extraction. For 34 million years, the stone stumps of ancient redwoods have held their ground at 8,500 feet in the Colorado Rockies, monuments to a world that vanished when volcanoes buried a lush subtropical forest under fifteen feet of mud. The name itself is French -- "florissant" means "flowering" -- and the irony is deliberate. What flowers here now are not living things but the impossibly detailed impressions of an entire ecosystem, pressed into paper-thin shale like flowers in a book no one meant to write.
