Large smoke plumes were produced by the Blackjack complex fire in southeasternGeorgia’s Okefenokee Swamp on May 8, 2002. Smoke from the fires, (whichcontributed to hazy skies across much of north Florida) is apparent in thisimage pair from the Multi-angle Imaging SpectroRadiometer (MISR). The fires started inlate April, and had grown to consume about 95,000 acres of swampland andlongleaf pine forest by May 20. Fire is a natural part of the swamp ecosystem,however, and a number of key plant and animal species within the OkefenokeeNational Wildlife Refuge ecosystems are dependent on fire for their survival.
The images illustrate the extent of the smoke using two types ofvisualization. The top panel is a natural-color view acquired by MISR’snadir (vertical-viewing) camera, and the lower view is a 3D stereo anaglyphcreated using data from MISR’s 46-degree and 70-degree backward-viewingcameras.
To facilitate stereo viewing, the images have been oriented with north towardthe left. Red/blue glasses are required to view the image in 3D, with the redfilter placed over your left eye. Information on ordering glasses can be foundat http://photojournal.jpl.nasa.gov/Help/VendorList.html#Glasses
The images represent an area of about 292 kilometers x 213 kilometers.
