Birthplace of famous Mars meteorite pinpointedhttp://www.newscientist.com/article.ns?id=dn8004

The site is in the Eos Chasma and there is a crater about 20 kilometers in diameter.

--- ALH 84001 is composed almost entirely (97 vol%) of orthopyroxene (Mason et al. 1992). A small region (625 kmē
) in Eos Chasma was identified as having a spectral component like the ALH 84001 end member ... ---http://www.higp.hawaii.edu/~hamilton/snc_maps.html
