But 25cm underground ? There could be only heat from meteorite, not from the
sun.

In Cali was for sure higher temperature than in Poland and Cali samples was
cold.
Baszkowka is 15kg compact stone that is big enough to still keep lots of
space cold, but it was hot.
Cali was 50-200g tiny stones that was cold, so they not grab enough heat
from ablation, or was cooled by air in "dark fall".

I think that this is good topic for a book or doctorate :)
