Snow-Talon
Fire, northern Lincoln Complex, MT
25 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 25, 2003 - 0530 MDT. (Courtesy of www.nifc.gov.)
|
LINCOLN COMPLEX, Helena National Forest. A
Type 1 Incident Management Team
(Studebaker) is assigned. This complex is comprised of the
Moose-Wasson and Snow-Talon fires,
ten miles west of Lincoln, MT. Backing fire with occasional
single tree torching was observed on
the Moose-Wasson fire. Fire behavior was more active on the
Snow-Talon fire; moderate rates of
spread with multi-tree torching and short range spotting
was observed. The Evergreen Cabins
area east of the Snow-Talon fire has been evacuated. Structure
protection is in place for 150
residences and 20 commercial properties.
