	SEM image (xxx) of red corrosion residue from Spider Cave. Note kaolinite crystals. Samples are Au-Pd coated. Photomicrograph by Mike Spilde and Diana Northup.
	EDS spectrum of barite crystals in a conglomeration of clay and iron from EY56 in the Western Borehole. Samples are Au-Pd coated. Analysis by Spilde, Northup, and Boston.
	EDS spectrum of inner wall rock from EY56 in the Western Borehole. Notice the presence of sulfur, potassium, and iron peaks in addition to the clay elements. Samples are Au-Pd coated. Analysis by Spilde, Northup, and Boston.
	EDS spectrum of red clay-like corrosion residue (sample RL4) from Red Lake passage in the Western Branch. Possibly a smectite or illite clay. Samples are Au-Pd coated. Analysis by Spilde, Northup, and Boston.
	EDS spectrum of red clay-like corrosion residue (sample RL4) from Red Lake passage in the Western Branch. Analysis is of a bright areas on back-scattered detection and shows more iron than the preceding sample area. Samples are Au-Pd coated. Analysis by Spilde, Northup, and Boston.
