Yesterday the Black Hills National Forest began the final phase of mitigating the downed trees, the fuels, left after a tornado passed through Spearfish Canyon along highway 14A between Cheyenne Crossing and Savoy southwest of Deadwood, South Dakota. There are about 200 piles (from Moskee Road to Sand Creek to Williams Gulch) that crews are planning to burn over the next few days.
The first photo shows the area after the tornado. The second shows piles of debris created so they could be burned later. In the third, one of the piles is surrounded by snow, and finally, they are being burned.
Igniting the fuels while there is snow on the ground greatly reduces the chances of escaping and igniting a wildfire.
