and in the “up-dip” direction (i.e. elevation is gained from 707 to 720). The amount of map distance between the outcrop and 720 structure contour is calculated from: Tan(55) = 13/x . x = 13/Tan(55) = 9.1 feet. Where x is the offset distance from the outcrop to the 720 structure contour. ................
