The Lindsey Creek Tree is the largest single-stem organism (tree) thus far known to have existed historically. It was a coast redwood (also known as California redwood), a member of the species Sequoia sempervirens. When it was uprooted and felled by a storm in 1905, its mass was at least 3,630 short tons, 3.3 million kilograms, or 7.26 million pounds; and its trunk volume was at least 2,550 cubic meters (90,000 cubic feet).[1]
