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.
