Enlargement shows some possible water flow directions in the fractured zone <br />along fractures and separated bedding planes within the fractured zone. Enlargement 2 shows <br />deflections of material in the near-surface and continuous-deformation zones and resulting tilt, <br />curvature, and strain. <br /> <br />
