Where can people find the tallest redwood trees?

M: Have you ever visited a redwood forest? I recently had a chance to go to Muirwoods National Monument north of San Francisco.
W: I’ve never seen one. I really can’t imagine how big they are.
M: The coastal redwoods are the tallest living things. Some are more than three hundred and fifty feet high. But none of the trees at Muirwoods are that high. (1) You have to go farther north in California to see the tallest trees.
W: You said that Muirwoods is near San Francisco? I guess it must be quite a tourist attraction.
M: Yes, it’s less than an hour’s drive away, so it’s easy to go to.
W: I’ve heard that many redwood trees are thousands of years old.
M: The oldest documented age for a coastal redwood is more than a thousand years. The trees at Muirwoods are 400 to 800 years old.
W: Why have they survived so long?
M: They have remarkable resistance to forest fires. (3) Their tough, thick bark protects the trees during a fire. The coastal redwoods also like a damp, foggy climate.
W: (2)Since Muirwoods is near foggy San Francisco, it must be ideal for the trees’ survival. I can’t wait to go and see them.
