These are redwood trees-the tallest of all trees-so tall in fact, that they can reach 385 feet. Their trunks can grow straight up for 150 feet before the first limbs branch out. One redwood, called the Rockefeller Tree, is as tall as a thirty-five-story skyscraper! Redwood are so special that in some parts of California state laws forbid people to cut them down. In other parts of the state, where logging is permitted, redwood is sold for outside building and outdoor furniture because it does not decay as quickly as other kinds of wood. Another giant California tree is the sequoia, a tree that is slighty shorter than a redwood. Sequoias prefer the colder, drier climate found father inland on the slopes fo the Sierra Nevada. They have thicker trunks and contain more wood than redwoods. In fact, it has been calculated that a full-grown sequoia contains enough wood to build thirty houses. The mammoth General Grant sequoia is almost a hundred feet around. It would take twenty people with arms stretched out to join hand around it. Cutting down any sequoia is not allowed. Redwoods and sequoias are among the oldest living things: the age of some of them exceeds three thousand years. One of the reasons they live so long is that when they are mature, their bark is more than a foot thick. Forest fires destroy other trees may scorch their outside bark, but do not affect them. The thick bark also helps them to resist diseases that kill other trees. Yosemite National Park and Sequoias National Park, both in eastern California, are the best places to see sequoias. The best palce to see redwoods is in Redwood  National park, in northwest California. In addition to its groves of redwoods, this park also contains forty miles of unspoiled Pacific coastline. These parks are among the most popular tourist attractions in the country.
