Virtually all puzzles in The Witness have some sort of underlying logic. However at the start of the game there is a cylinder pillar puzzle that has no identifiable logic or solution, just two rows of upward pointing triangles from top to bottom.
All game walkthrough solutions indicate that multiple turns are needed to solve it, but there is no symbolic marking on the pillar show these turns.
Some puzzles use environmental references nearby, but there are no identifiable nearby objects that help to solve the column.
What am I overlooking?
