Othersville submarine dock

• The submarine dock was seen on S03E13 (at night) when Locke seemed to blow up the sub
• Screenshots are taken from Juliet arrival on the island (see S03E16)
• It looks like it's located in a river or lake (see screenshots)

Pala Ferry dock

• Shouldn't be too far away from the Capsule dump and the Pearl station
• Huge mountain/cliff to the right (see first screenshot)
• Edit (02/26/07): MikeQuinn007 found another "X" on Danielle's map (see screenshot by MikeQuinn007). Maybe this marks the position of the Pala Ferry.
• Edit (02/26/07): Sun, Jin and Sayid arrive in the morning at the Pala Ferry in S03E02 (Sun mentions her "morning sickness"). The 4th screenshot is taken shortly before their arrival. This could indicate that the mountain slopes in the background of this screenshot are facing east.
