October 31, 2022 - Smoldering Fires under Fresh Snow in Idaho

Snow

Winter-like weather brought a layer of fresh snow to the mountains of Central Idaho on October 25-26, 2022, slowing the active fire season. Despite the welcome precipitation and chilly temperatures, several wildfires continued to smolder. According to the National Interagency Fire Center (NIFC), four large wildfires were burning in Idaho on October 27. They also listed activity on one large, 100 percent contained wildfire. On October 30, the Idaho Bureau of Land Management (BLM) listed 54 ongoing fires across the state. The NIFC only lists large fires, while the BLM list also includes smaller blazes.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Aqua satellite acquired a true-color image of the snow-swept mountains of Central Idaho on October 27. Multiple red “hot spots”, each marking high temperatures typical of active fire, speckles the otherwise winter-like scene.

The largest fires visible in this image include: the Norton Fire, which has burned 9,278 acres and is 60 percent contained; the Patterson Fire at 263 acres and 10 percent containment; the Ross Fork Fire at 38,013 acres and 85 percent containment; and the Woodtick Fire on 9,834 acres with 50 percent containment. The Norton, Patterson, and Woodtick Fires are located in the Salmon-Challis National Forest while the Ross Fork Fire is active in the Sawtooth National Forest. The Kootenai River Complex in the Idaho Panhandle National Forest has been 100 percent contained. That fire has scorched a total of 25,401 acres.
