You folks are right. The salt textures on the crust are a common feature of antarctic surface finds. Unfortunately the in situ photograph of ALH761 in the Photographic Catalog of The Selected Antarctic Meteorites is of poor quality, at least in my copy. Note the "mismatched saw cuts" on page 52.
 
I have uploaded the photos for those interested:
 
http://www.meteorite-recon.com/en/meteoriten_ALH761.htm

The Catalog of Yamato Meteorites (Tokyo 1979) gives a brief description of the mass that was found by a team consisting of K. Yanai, the grandmaster W. Cassidy himself and E. Olsen. It says: " Large mass with abraded crust". A small b&w photo is on plate 9. The entry continues: "Cut in two parts, 9671g (Allan Hills 761,1) and 10244g, Allan Hills 761-2 (USA)."
 
Cheers

I'm away from my photographic catalogs, but maybe someone else can check their own. I believe either the Catalog of Yamato Meteorites or Photographic Catalog (1981) show the entire mass. I'll check when I get home...
