Were these taken on Monday? I thought I saw a truck by the woodpile that goes up to the Old Big Oak Flat Road. The beetle kill has been huge and has effected more than just Yosemite. Prior to the 1870's Yosemite Valley was much wetter and had more oaks and fewer pines. Thanks to Galen Clark, the terminal moraine was blasted so that the river valley would drain. This was an early mosquito abatement program.
