On Sunday the Dominic Point fire was discovered at 3 p.m. about 12 miles northeast of Hamilton, Montana (map). Likely a holdover from a lightning bust from a couple of days ago, it appears to be cranking, and is in hot, dry, inaccessible terrain in the Bitterroot National Forest.
The photo was taken about two hours after the fire was reported.
UPDATE at 9:16 a.m. MT, July 26 : more information, including a map of the Dominic Point fire, is now available.

Windy with lightning this evening, 4 or 5 raindrops, 80 degrees in the valley, overcast all day. Enough wind about 1800 to probably stop the air show. The lookout guy from Willow Mt. Lookout was on KPAX TV (CBS MSO) and said flame lengths yesterday ran 100+feet with fire behavior like the 2000 fires.
