The closure began July 25 because choking smoke from the Ferguson Fire had filled the iconic Yosemite Valley, creating unhealthy conditions. Firefighting operations had also limited access to Highway 41/Wawona Road.
On Tuesday, park officials also announced that they had added the Hetch Hetchy Valley to the list of areas closed to the public.
#YosemiteNationalPark extends its park closures. Adds Hetch Hetchy closure to the list . Park officials say the closure will last until Sunday due to heavy smoke and firefighting efforts. They will determine whether they reopen on Sunday, August 5th. @ABC30
