Palau, 2011

Blue Corner divesite map located at Sam's Tours. On the upper right of the map are shown the four blue holes leading through the reef to a subway stop sized cavern whose large exit is between 75' and 90' deep. When we dive the blue holes, we exit the cavern at this depth and then drift and swim along the vertical wall toward the tip of the blue corner (where the top of the reef is 65' deep).
