The Dawson Straits, seen in this NASA Landsat image, is located between eastern Fergusson Island (upper left) and northwestern Normanby Island (lower left) in the D'Entrecasteaux island group. The area contains a volcanic field with several young volcanic centers that erupted rhyolitic obsidian flows. Mount Oiau is located on the narrow peninsula (left center) forming the southernmost point on Fergusson Island. A large crater is visible on Dobu Island, southeast of Oiau. Young volcanic rocks are also found on Sanaroa Island (upper right).
