The Dishchii’bikoh meteorite fall in the White Mountain Apache reservation in central Arizona has given scientists a big clue to finding out where so-called LL chondrites call home. The low precipitation rate in these areas preserves the meteorites, allowing for their accumulation over time, and the lack of vegetation makes the meteorites easier to find.
