How about in amber then? How long might we expect DNA to remain intact perfectly encased in amber?

You won't find DNA that isn't in contact with a lot of water in nature, unless something actively extract the water.

Amber is heterogeneous in composition, but consists of several resinous bodies more or less soluble in alcohol, ether and chloroform, associated with an insoluble bituminous substance. Amber is a macromolecule by free radical polymerization of several precursors in the labdane family, e.g. communic acid, cummunol, and biformene. These labdanes are diterpenes (C20H32) and trienes, equipping the organic skeleton with three alkene groups for polymerization. As amber matures over the years, more polymerization takes place as well as isomerization reactions, crosslinking and cyclization.

CAN YOU REALLY PULL A "JURASSIC PARK" AND EXTRACT DNA FROM BUGS FROZEN IN AMBER?

The questions still seems reasonable? Maybe there exists some geological processes minerals deposits that absorbed moisture? Some kind of geothermal heating (although maybe that would just make steam permeate the surrounding area), an asteroid fragment from the Chicxulub impact that carried DNA into space??
