We all took Grandma to visit Muir Woods, named after one of our first and most important naturalists in California, John Muir. He was pretty much the first guy to point out the the settlers of the West and the gold rush mobs, that preserving some forests was extremely important. Thank goodness for him.
The redwoods are huge. The big ones have been alive since 900 AD, and earlier. Since before our familiy was known in the Domesday Book. We saw one 15 foot slab that had been cut away. It looked like a fragment of the tree, with thousands of rings. In 1880 that would have been great timber supply. Today the live trees and the forest are a monument to natural history and national pride.
