What is the overall air quality and visibility like right now? I am seriously considering getting a walk-up permit Sunday or Monday to either Sunrise Trail>Cloud's Rest>Half Dome>Cathedral Lake or Tuolumne Meadows>Donahue Pass>Red's Meadow.
The last time I was on HD there was a wildfire nearby and it ruined the experience, I don't want to go up there is visibility isn't good. And right now the weather report in Mammoth Lakes shows "Widespread Haze" every day.
The alternative is to go later in September but the weather can be dicey and very cold, any recommendations?
