This mysterious map can be found inside the cable car station at the top of Mount Trinidad. The map seems to outline a series of clues to a puzzle that may be unsolvable. There are three paintings at the foot of the mountain, including UFO, egg, and jetpack.

We know there are Ufos, so it's entirely possible that there is a jetpack in the game. For now, the mystery of SAN Andreas' largest mountain, Ciriad, will remain a potential myth.
