The Golden Spiral was a significant part of the design of Turbulent Lands V. The Spiral begins at the upper left and continues down to the bottom center and back up to the upper right. The polar point of the spiral is seen at the upper right. It could have been a little lower. The design did not use the Dynamic Symmetry armature. However it's noteworthy that many of the cliff lines do seem to align with armature lines.
Aspect Ratio, 24/15=1.6 near PHI.
