South Georgia's hidden glacial past

The British Overseas Territory of South Georgia was covered by a giant ice cap 20,000 years ago.

Scientists have mapped the troughs cut in the seafloor by great glaciers.

Evident in these channels are the countless, tell-tale markings of bulldozed sediments known as moraines.
