The Hamilton Air Quality Monitor hourly readings climbed into the "Unhealthy" category Sunday afternoon, August 28. The readings stayed at that level until about 3 a.m., when the smoke disbursed somewhat. Hourly exposure readings are in the "good" and "moderate" levels Monday.

NASA satellite data showed the Moose wilderness fire burning actively again to the south and north Sunday It seems to be the source of most of the smoke coming into the Bitterroot Valley. KLYQ has no current size estimate of that Idaho blaze, which is about eight miles from the Bitterroot National Forest. The Nez Perce-Clearwater National Forest also set off a prescribed burn this weekend.

The Roaring Lion fire, meanwhile, is downsizing its firefighting force. This morning, the daily report showed 55 people assigned to the fire south of Hamilton. Two hot spots were attacked Sunday with helicopters and ground crews. Fire lines on the north end of the fire area are being repaired, since they are no longer needed.

All area closures remain in effect.
