Here's another chance to play geographical detective! This false-color image
was acquired by the Multi-angle Imaging SpectroRadiometer (MISR) in late June,
2002, and represents an area of about 292 kilometers x 370 kilometers. Data
from the near-infrared, red and blue spectral bands of MISR's downward-viewing
(nadir) camera are displayed as red, green and blue, respectively, causing
highly vegetated areas to appear red.
