The fire was active when I arrived last Sunday at West Yellowstone. It was apparently caused by a lightning strike a few days to a week earlier. It was mostly put out by firefighters and the storm that went through Wednesday. From what I heard from the rangers, it burned across the road from West Thumb to Fishing Bridge, causing this road's closure. When I left, the road was scheduled to be closed most of the day for debris and dead tree removal.
Thought about diverting to check out the the brothels in Wells, Elko, Ely on my way home to southern California, but decided to pass.
