GBY is Gesher Bnot Ya'akov, an archeological site in Israel, it’s in the first paragraph of the abstract.

Yes, it did say the name and the name clearly seemed to be in Hebrew, but _where_ it actually was wasn't clear to me.

The site also has been dated to ~790,000 years old. Also was hard to find in a quick skim. So, direct evidence of the types of firewood humans have been using for the better part of a million years. Neat.
