Here, along the banks of Redwood Creek, are the world's tallest known trees. The tallest is 368 feet (112.3m) and several of its neighbors are not far behind. Imagine a tree as tall as a 30-story office building, or much longer than a football field. That is what you see in this picture, but without some means of comparison, their height does not seem that great. There has been some controversy about what tree actually holds the record. Not long after the Redwood Creek grove was discovered someone else claimed to have found an even taller one, but its accurate measurement showed it to be "only" 70 m high. Loggers is Washington state and British Columbia claimed to have felled trees of Douglas fir (Pseudotsuga taxifolia) over 400 feet long. The Australians have long claimed that a gum tree ( which grows in a similar environment to the coastal redwood), Eucalyptus regnant, is the tallest tree. However the tallest accurately measured eucalyptus tree (346 feet) falls short of the coast redwood by 7 meters (22 feet).
