PBS did a program on Tunguska years ago. (It might have been on the "Nova" program.) Russian scientists visited it several times, and even in the films as recent as the 1980s, it was a very difficult, cold, wet, and remote area, full of big hungry mosquitos. (Like the Alaskan variety.) I remember also that they still found evidence of fallen trees. The Russian theory was that a comet or very small asteroid coming in at an unseen angle, exploded above the tree tops.
