	SEM image (9500x) of unknown bacteria bridging between rocks collected from red-brown corrosion residue in Snowing Passage in the Southwest Branch. Photo by Diana Northup and Mike Spilde.
	SEM image (23,000x) of unknown bacteria from red-brown corrosion residue collected in Snowing Passage in the Southwest Branch. Note iron oxide stars nearby. Photo by Diana Northup and Mike Spilde.
	SEM image (13,000x) of unknown bacteria and iron oxide stars in the red-brown corrosion residue from Snowing Passage in the Southwest Branch. Photo by Diana Northup and Mike Spilde.
	SEM image (5,000x) of several strings of unknown bacteria scattered across red-brown corrosion residue from in Snowing Passage in the Southwest Branch. Photo by Diana Northup and Mike Spilde.
	SEM image (10,000x) of chain of bacteria on calcite rock on Spider Cave. Sample is Au-Pd coated. Photo by Spilde, Northup, and Boston.
	SEM image (5500x) of small "iron nodules" (EDS analysis) on calcium carbonate. Some evidence of corrosion pits. Sample (SW3) is of salmon-colored chunks of rock from the corrosion residue in the FN survey near FNH2 on the way to Big Sky camp. Photo by Spilde, Northup, and Boston.
	Closeup SEM image (16,000x) of the "iron nodules" in the preceding image. The size and collapsed look suggest that these could be bacteria. Photo by Spilde, Northup, and Boston.
	SEM image (1000x) overview of the preceding two images. Photo by Spilde, Northup, and Boston.
