[ 01 ] THE PLACE

The Lena is one of the great rivers of Siberia. Before it reaches the Laptev Sea it breaks into a delta of hundreds of channels and many thousands of small lakes, set in permafrost tundra.

In near-infrared the living tundra turns crimson and open water goes almost black, because water absorbs nearly all of that light. The contrast lets us trace every channel on every pass, and see which ones moved since the last.
