shows foliation in the rock in a side view at 118 feet below land surface. Image B shows subhorizontal fracture opening at about 155 feet below land surface formed parallel to compositional layering. White floculant covering fracture is probably iron bacteria. Image C shows a high-angle joint (dashed line) intersecting the borehole wall at about 207 feet below land surface. Image D shows large openings caused by chemical dissolution around steeply-dipping joints at about 463 feet below land surface. shows a side view into one of the large openings in Image D. Image F shows an open joint at about 489 feet below land surface. Image G shows high-angle joints (black arrows) intersecting the borehole wall at about 511 feet below land surface.
