Caption: Landsat-7 satellite image showing the June 19, 2001 conditions on the land one day after the June 18, 2001 Siren, Wis. tornado. The image covers an area of northern Wisconsin approximately 50 miles in the east-west direction and 20 miles in the north-south direction. The bright path of greatest destruction shows a change in land reflectance and can be seen running roughly parallel to Highway 70, from just east of Alpha to the eastern edge of the image, just southwest of Spooner, Wis.

Caption: This comparative statistical analysis of the change in land reflectance between two Landsat-7 satellite images, one on May 18, 2001 and the other on June 19, 2001, shows the change in land conditions associated with the June 18, 2001 Siren, Wisconsin tornado. The bright path of greatest destruction shows a change in land reflectance and can be seen running roughly parallel to Highway 70, from just east of Alpha to the eastern edge of the image, just southwest of Spooner, Wis. This image shows an enlarged view of the tornado's path centered on Clam Lake, just east of Siren.
