Why are East and West reversed on some compass roses?
The reversed compass rose causes initial confusion with novices, but in use it is obvious why the compass rose must have East and West reversed. When you are sighting directly North, the compass needle will point to North. If you turn 90 degrees to your left, you will be sighting due West, but the compass needle rotated 90 degrees to the right, which reads West on a properly reversed compass rose.
