It turned out that the clouds that turned us around on the 12th were the start of a bit of a storm, so it's probably better that we were out there all alone anyway. On the 19th the weather had finally improved enough to make a second attempt to go out to the iceberg. This picture shows the Erebus Ice Tongue which is a rather unique feature where a glacier flows out into the ocean. In the ocean, nothing is constraining the sides of the glacier (valley walls or slower flowing ice would constrain it when it was on land). This allows the glacier to spread out from side to side and form these undulating shapes. There are some neat caves along the edge of the glacier but I haven't been to any of them.
