Game of chess anyone?

This is pretty cool. What we are seeing here is an area of 23 x 20 kilometres along the Idaho-Montana border crammed between Clearwater and Bitterroot National Forests. You will notice a checkerboard pattern within the land area; each square covering an area of around 1.6 x 1.6 kilometres. Each square hosts trees, which are harvested at different times and have different timber densities and regrowth stages. As a result, this natural pattern has formed.

The image was taken with the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on-board Terra, the flagship satellite of NASA’s Earth Observing System (EOS).
