[meteorite-list] Tunguska Questions

[Mr EMan]

A couple of points related to the questions posed 

The Ries impactor is believed to have hurled multi-ton limestone sections up slope onto the Alps, 100km/60miles away. It was far larger than Tunguska and a different scenario all together save for it could have been a dead comet and related to the Carbonaceous meteorites.

I believe that Taggish Lake Redeux within a few months found all of this carbonaceous meteorite left originally on the surface had turned entirely to "mud".

So other than sediments it is perfectly plausible that Tunguska left no macro objects that survived long.
