Interesting new article re the fins and cracks in Meridiani, from UC Davis:

Soggy Sands of Mars?
http://www.news.ucdavis.edu/search/news_detail.lasso?id=7698

"Cracks and fins in the sand in an American desert look very similar to features seen on Mars and may indicate the recent presence of water at the surface, according to a new study by researcher Greg Chavdarian and Dawn Sumner, associate professor of geology at UC Davis. "Recent, as in ongoing now," Sumner said."
