A prescribed fire unit called RX Red Rocks Fall Units was reported in Jefferson County as of September 30, with the official acreage listed at zero and the cause listed as undetermined.
The "RX" designation indicates the fire is a planned prescribed burn rather than a wildfire, though the undetermined cause notation and zero-acre report suggest the unit may have been logged before ignition or shortly after a test burn. Jefferson County sits just south of Lewis and Clark County and borders the Helena Valley, making fire activity there of routine interest to Helena-area residents.
No containment or evacuation information was associated with the report. Residents with questions about prescribed burn schedules in the area can contact the relevant land management agency for the Red Rocks unit.
