[3] The feature was named by the UK Antarctic Place-names Committee in 1958 for James Byers, a New York shipowner who tried unsuccessfully in August 1820 to induce the United States Government to found a settlement in and take possession of the South Shetland Islands.
It has diverse and well-developed vegetation, numerous lakes and freshwater pools which support the restricted-range insects Parochlus steinenii and Belgica antarctica, and well-preserved sub-fossil whale bones in raised beaches.
It also has the greatest concentration of historical sites in Antarctica, containing the remains of refuges, with their contemporary artefacts, and shipwrecks of early 19th century sealing expeditions.
[6] Byers Peninsula is part of the mise-en-scène in the Antarctica thriller novel The Killing Ship authored by Elizabeth Cruwys and Beau Riffenburgh under their joint alias Simon Beaufort in 2016.
