State wildfire tracking data turned up prescribed burn activity across at least four counties this week — Jefferson, Powell, Broadwater, and Lewis and Clark — with units bearing names like RX Red Rocks Fall Units, RX Flint Foothills, Bonanza Ridge RX, and Beartrap Gulch RX. The Bonanza Ridge burn in Broadwater County, just east of Helena, was the most substantial on paper at 550 acres. The others, however, reported zero acres burned at the time of logging, which is worth noting for residents trying to make sense of smoke in the air or questions about fire activity near their communities. Zero-acre listings can reflect burns that haven't ignited yet, reporting lags, or units being held in reserve — the data alone doesn't always tell the full story. Add to that the High Wind Warnings that swept across north-central Montana late last week, issued by the National Weather Service office in Great Falls, and the regional fire picture looks like one worth keeping an eye on heading into October. The National Weather Service Great Falls office was among the week's most-cited entities with 109 mentions, a reflection of how much weather drove local coverage.
