, Mackellar, and Ezcurra. A mariner's guide to the region pronounced the bay to have the best anchorage of any in the South Shetlands, "being well-sheltered all around and having moderate depths over a bottom of good, stiff clay. Ice from the glaciers is frequently troublesome." Chilean scientists have claimed that Amerinds visited the area, due to stone artifacts recovered from bottom-sampling operations in the bay. however, the artefacts — two arrowheads — were later found to have been planted.
