WebNote the vertical scale that separates the #14 and #4 logs that marks the elevation of subsurface strata. The sign of the scale is negative (-) because these elevations lie below sea level, the datum. Each of the well logs (excepting the #14) have been positioned according to their subsurface elevation, thus this is a structural cross section.
