Satellite Image of the Smokies

This is an image from Landsat 7. According to NASA's Earth Observatory website,

This Landsat scene shows the park, with its southern boundary along Lake Fontana. The central high ridgeline through the spine of the park is evident, with the light green forests of the lower lands and slopes giving way to the darker green regions of the ridges and peaks. The lower region forests are dominated by deciduous leafy trees (which strongly reflect near-infrared radiation, which is colored green in this image). At higher altitudes, deciduous forests give way to coniferous trees like Fraser Firs, which are less dramatically reflective at near-infrared wavelengths, and so appear darker in the scene.
