the elevator is pretty massive its probably the biggest one in the game and as such could easily be mistaken for just a wooden floor
im not sure if its possible to go up it and jump of but if it is there should be a call button around
the east side of the map is inaccessible as far as im aware
heres a map with the elevator marked
