Radio tower map
Ben had possession of a map of the Island that he used to plot the route he and Alex would take to intercept the survivors on their way to the radio tower. He did this by drawing lines in red pencil across the map, thus implying that the map was to scale. He drew from the beach camp and from the Others' location, keyed as Pascal Flats. ("Through the Looking Glass, Part 1")
After refusing to lead the survivors to his supposed balloon (which belonged to the real Henry Gale), Ben drew a map to it after Ana Lucia offered him an ultimatum. ("The Whole Truth") The map covered an area that could be crossed in about a day's hike (from the camp to the clearing). The map noted various geography on the Island including mountains, the jungle, the forest, a ridge, a stream, and a cliff. Ana Lucia, Sayid, and Charlie followed the map to a location that at first glance did not reveal the balloon. It was shortly found, however, and they proceeded to excavate the presumed grave of Henry Gale's "wife". Looking to find a woman, they instead found a man: the real Henry Gale. After discovering that Ana Lucia had led the search in secret, Ben admitted to being an Other. ("Lockdown")
- The balloon map was drawn on the back of the title page of The Brothers Karamazov.
- The survivors did not question the fact that "Henry" was able to draw the balloon map, even though he was unconscious when taken to the Swan.
- The radio tower map that Ben drew in "Through the Looking Glass, Part 1" was shown twice, at approximately 22:53 and 36:28. These two maps are not the same prop; the red lines drawn on the two maps differ slightly.
