In 1998, the Patriot Hills area of the Ellsworth Mountains of Antarctica was selected by the Planetary Studies Foundation (PSF) of Algonquin, Illinois USA as a potential site for the collection of meteorites. The eight person expedition searched several sites in and around the Patriot Hills, but met with little success in finding meteorites. In January 2000, the PSF chose to continue its efforts in the Thiel Mountains, an area of known meteorite concentrations. The goal was to collect as many meteorites as possible by extending the previously searched blue ice areas at the Moulton Escarpment. Earlier search teams collectively recovered 36 meteorites. In the five days of fieldwork at the Moulton Escarpment, the PSF team collected 19 confirmed stone meteorites, and 2 possible achondrites. Upon return to Patriot Hills another small stone meteorite, consisting of 6 small fragments totalling 1.7 grams, was collected in the Morris Moraine where a 23 mg meteorite fragment was found in 1998. In addition, ice samples were collected at Patriot Hills, Thiel Mountains, and the South Pole. The presence of several micro-organisms has been identified in these samplings and will be evaluated as possible contaminants of Antarctic meteorites.
