Maybe it's been mentioned here but I haven't seen it. Did just read on-line that Yosemite is canceling all of the back country backpacking permits for the Tuolome (sp) Meadows area and the park. I have relatives in the San Francisco area, where a state of emergency has been declared because they get 85% of their water and their hydropower from the Hetch Hetchy Reservoir and it's endangered by the fire. And yet, I did also read that in the Yosemite Valley the air is clear and no sign of the fire, but the smoke has gone over the Sierras into Nevada and is shutting down things there.
