Scoria
Scoria is a volcanic rock containing many holes or vesicles. It is most generally dark in color , and basaltic or andesitic in composition. Scoria is relatively low in mass as a result of its numerous macroscopic ellipsoidal vesicles, but in contrast to pumice, all scoria has a specific gravity...

and Wilson Stream
Wilson Stream
Wilson Stream is a meltwater stream which flows from the ice-free lower west slopes of Mount Bird, to the south of Alexander Hill, and over steep sea cliffs into Wohlschlag Bay, Ross Island. Mapped by the New Zealand Geological Survey Antarctic Expedition , 1958–59, and named by the New Zealand...
