The Going To The Sun Road is now open all the way through. There are nightly closures at the moment. The fire burned a large chunk of the woods along the road between the Wild Goose Island pullout and the Gunsight Pass/Jackson Glacier Overlook pullout. Almost that entire stretch is burned. Everything around Sun Rift Gorge is burned. The slopes above Rising Sun Motor Inn are burned, and so it the drainage up to Otakomi Lake. Looks like it burned right down to ST Mary's lake. The area around St Mary Falls is burned pretty bad as well.
The rumor is that the Reynolds Creek backcountry site is where the fire started, and that that area is completely burned. But the Gunsight Trailhead is not burned, and it appeared that most of the route up to Gunsight Lake avoided the fire. At least that's how it looked from driving past it.
Here are 2 shots of the valley as we drove into St Mary's a week ago. Most of this is out now.
