Hobble Fire, Sweet Grass County, MT
18 August 2003


As viewed by the FireMapper™ Thermal-Imaging Radiometer

Images were collected from the PSW Airborne Sciences Aircraft and disseminated in part by satellite communications in near-real time. FireMapper measures the radiance of emitted thermal-infrared light, which readily penetrates smoke. False-color images shown here depict the apparent surface temperature (in Celsius) as estimated from radiance and a simple black-body model. Warmer tones represent recent or active combustion; areas of gray are cooling ash or warm bare ground (see chart below). Low temperatures of unburned forest and cool ground are shown in green. Images have been geographically referenced. Vertical exaggeration in 3-d views is 1.5 to one unless otherwise noted.

Narrative from the INCIDENT MANAGEMENT SITUATION REPORT
MONDAY AUGUST 18, 2003 - 0800 MDT. (Courtesy of www.nifc.gov.)

HOBBLE, Southern Land Office, Montana Department of Natural Resources & Conservation. A
Type 2 Incident Management Team (Larsen) is assigned. This fire is in timber and grass, six miles east of Greycliff, MT. This fire was declared contained on August 16. However, wind gusts of 30 miles per hour caused the fire to jump containment lines. The fire made significant runs to the east. Stephens Hill Road is closed and residences along that road are evacuated. Two
residences and five outbuildings were lost. Structure protection is in place for eight residences.
