The Coast Redwood and the Giant Sequoia are related, massive, long-living softwood trees growing on the west coast of North America. Their wood is straight, resistant to pests, and easily splittable, but they take centuries to mature. Specimens may exceed five meters in diameter and a gigagram in mass.
Widespread exploitation of the trees began with Anglo-Americans immigrating and building sawmills around the 1840s. Many of the few remaining specimens are now protected in parks.
Minimal tools and technique are needed to cut down a young redwood, but harvesting a mature one and transporting its wood, even in pieces, is dangerous and technical. Besides gigantic saws, it can take wedges, sledgehammers, drills, platforms, and maybe more.
When did the large trees become possible to harvest and handle? Is it known who was the first to cut down a mature one?
