These Multi-angle Imaging SpectroRadiometer (MISR) images acquired
on July 27, 2001 (Terra orbit 8554) show the area around Jackson
Hole, Wyoming, where the Green Knoll forest fire has raged for
many days.
Due to this year's low humidity, officials from the Grand Teton
National Park and Bridger-Teton National Forest Interagency Fire
Management Office announced a high risk for the area. The Green Knoll
blaze is suspected to have been sparked by a campfire, and is located
a few kilometers southwest of the town of Jackson. About 4600
acres have been scorched by the fire. Mandatory evacuations of some of
the subdivisions near the town of Wilson were ordered, and on July 27
the fire had crept to within 300 meters of buildings. By July 29, the fire
was reported to be 60-70% contained, thanks to the valiant efforts of over
1000 firefighters and the assistance of about one-fourth of the
nation's air tankers. Improved weather conditions, including lighter winds,
cooler temperatures and higher humidity, also helped matters. More information
is available at the Grand Teton National Park and US Forest Service shared
interagency website, http://www.tetonfires.com.
At the left of this image set is a true-color view from MISR's 70-degree
forward-viewing camera, covering an area of about 240 kilometers x
340 kilometers. The oblique angle of view accentuates the visibility
of smoke, which can be seen as a thin bluish-white haze over the Jackson Hole
valley. At top right is a cropped version of this picture, rotated counterclockwise
to facilitate comparison with the stereo anaglyph beneath it. The anaglyph
was created from MISR's 70-degree and 60-degree forward views, and requires
a rotated orientation in order to produce a 3-D effect. Viewing the anaglyph
in stereo helps to visualize the local topography and to differentiate the
Green Knoll smoke plume from the higher nearby clouds. Stereoscopic viewing
requires red/blue glasses with the red filter placed over your left eye.

Yellowstone Lake is visible at the center of the left-hand image, and is
surrounded by Yellowstone National Park, the world's oldest national park.
To the west of Jackson Hole is the Teton Range, with the peak of Grand Teton
rising 4196 meters above sea level. At the lower right of the left-hand image
is the Wind River Range, containing Gannett Peak, the highest point in Wyoming
at 4207 meters. The Continental Divide runs through this range.
