    A fragment of the cosmic body that allegedly exploded over Siberia in 1908 may have impacted the waterlogged surface and formed a lake. The morphology of the lake is suggestive of an impact crater, and radar scans have revealed a density anomaly (Reflector T, Fig. 6) at the bottom of the funnel shaped lake, that would be consistent with a metallic object.

    The comparison of the lake’s profile with that of the Odessa impact crater (Fig. 10) is striking.

    Interesting. I believe the current best-guess on Tunguska is that it was a small comet or some such? Or is meteorite still holding sway? Of course, in the pseudo-science suburbs there are always the alien spacecraft advocates...

    Well, the reflection from the object does have a smooth convex shape to it...sort of inverted saucer shape... :P
