A map/diagram of the island is revealed during the hatch lockdown. It is full of information regarding the experiments on the island including the other hatch locations, the reason for the experiments and the locations of other important island elements. There is also Latin that other websites have translated that lead us to more clues about what is going on on this island. There are things such as a zoological experiment, gene therapy and climate control discussed on the map. A fourth DHARMA Logo is indicated on the map/diagram Locke sees on the door: a flame. We have had no previous knowledge of this logo. The other logos that have been revealed are the Swan, the Arrow, and the Staff.
