California redwood trees (
Sequoia sempervirens) are some of the longest lived plants on the planet. This tree fell in a local storm in the 1930s and the cross cut is displayed at Joaquin Miller Park in the Oakland hills.
The crack in the middle of this huge crosscut dates to 700 AD. The tree rings show when the Norman invasion of England occurred, Columbus sailed to the New World, and the Pilgrims landed in what is
now Cape Cod Massachusetts. While almost all of the first-growth redwoods were chopped down for building projects in the late 19th and early 20th centuries, Oakland still boasts the largest stand of second-growth redwoods in California.
