The prescribed fire scheduled for this week in Yosemite Valley has been postponed until further notice due to the Carsten Fire, which is burning about 40 miles outside (west) of Yosemite. Currently, all roads to Yosemite are open. Yosemite is receiving some smoke from the fire, especially overnight and in the morning. You can check on visibility in the park by viewing our webcams at http://www.nps.gov/yose/photosmultimedia/webcams.htm.
