Kate's map was a hand-drawn map made by Kate for Jin and Sun so that they could find their way to the barracks to join up with Locke's group. Kate said, "Once you hit the stream you want to head northwest. Pretty much in a straight line for about a day and a half." ("Ji Yeon")
- The Barracks were north/northwest of the beach camp.
- The Barracks were said by Kate to be a day and a half from the beach camp. The estimate given may have been based on Sun's condition (pregnancy) rather than the normal travel time.
- On close inspection of the image of the map, it can be seen that an imprint from a very similar map had been drawn onto another page, leaving an imprint onto the map shown.
