What to See

The slab was put on display after the tree fell in 1930. Each concentric ring records one year of growth, and the full count came to 1,021 years. For scale, coast redwoods typically reach about 600 years and some live more than 2,000. The exhibit gives a direct way to read how long a single redwood can stand and grow in this forest.
