Giant sequoia is world's biggest tree
Giant sequoia is world's biggest tree Dating back to around 200 B.C., and over 83 metres
tall, the largest tree in the world can be found in Californian's
Sequoia National Park. It is called the "General Sherman Tree" and
is a giant sequoia. Giant sequoias do not grow as tall as redwoods
do, but their trunks are much larger. Some of their trunks measure
30 metres around at the base! The name "sequoia" comes from the
name of a Cherokee Indian who invented a written alphabet for his
native language. 17 JULY 1999
