I went by this fire on 395 at 1:30 or so on my way to Mammoth for the night and a Emigrant Wilderness backpack beginning Saturday. I saw the first whiffs of smoke and emergency vehicles blocking the road as I approached Tom's Place. I feel for the backpackers exiting Mono Pass (and intending to drive home) or the Little Lakes Valley hikers and campers, now that the road is closed.
