Well, if you typed it, you should know it but let me tell you a bit about the name.
The name "Yosemite" means literally "among them are killers" or "there are killers among them" and is a corrupted form of an American Indian word used to describe the Ahwahneechee people.
The Miwok tribe called the residents of that valley the "Yos se' meti" -- a perforative that literally means "they who kill." The actual residents there called the place "Awo mi", literally meaning "large mouth."
American miner L.H. Bunnell, after attacking the tribe, decided to give the valley the name "Yosemite" as (somehow) an "American" name.
