True. The Antarctic provides a whole range of meteorites, common and
uncommon, concentrated in a relatively small area. While the Mars
meteorites are important, there are many other interesting meteorites
as well.

Six of the known 12 Mars meteorites have been recovered from the Antarctic.
In fact, the last 6 Mars meteorites came from there. The last non-Antarctic
meteorite was Zagami which fell in 1962. You don't
know ahead of time what kind of meteorite will be recovered from the
Antarctic, but as long as you keep looking there you're bound to find
new Mars meteorites. And again, the other meteorites are scientifically
important as well.
