A record tree: the coast redwood
AI-generated conceptual illustration showing a coast redwood beside a human figure and a 35-storey-building silhouette to communicate scale. It is not a photograph of Hyperion, a measured specimen, or to scale as a scientific diagram. Prompt: “Conceptual natural-history illustration, not documentary: a very tall coast redwood in a misty Northern California old-growth forest, tiny human silhouette at the base and a subtle 35-storey-building silhouette for scale. Do not depict a named record tree, exact location, measured data, signage, labels, or text. Respectful museum illustration, vertical 4:5 composition, muted green and fog palette.” Generated 2026-10-29; no external source or documentary role.
The tallest tree currently known to the U.S. National Park Service is a coast redwood, at about 379 feet, or 115.5 metres. A coast redwood named Hyperion was measured at 379.1 feet by researcher Stephen Sillett in 2006. This is a height record for a particular tree, not for all plants, and the record can change as tree crowns grow or break.
