If you are suddenly awaken on a deserted island what is one that you can use to determine direction?

If you find yourself on a deserted island, you can use the position of the sun to determine direction. The sun rises in the east and sets in the west, so by observing its movement across the sky, you can establish a basic north-south line. Additionally, if you have a watch, you can use the hour hand to find north in the Northern Hemisphere by pointing it at the sun and then bisecting the angle between the hour hand and 12 o'clock.
