I live in Kalispell 30 minutes outside Glacier Park and the smoke from fires is very light here and in the park. Even the most susceptible to smoke-related health problems aren't suffering now. Mid-September should be much better as cooler temperatures and higher humidity rolls in.
For an update on the Sprague Creek Fire inside the park, visit the
Montana Inciweb Fire Website. It's updated daily with fire conditions for all fires in Montana.
We will probably see you in the park, as we will be camping there at the same time.
Incidentally, I'm a 911 Dispatcher and took many of the 911 calls the night the Sprague Creek fire started, which was during a major lighting storm.
