Agüero Point etc. Several Argentine names commemorate crewmen of the Argentine Navy Lockheed Neptune aircraft that crashed in poor weather on the then uninhabited island on 15 September 1976, killing 10 aircrew and a civilian television cameraman. Features like Point Smellie and Willan Nunatak are named after British scientists who have carried out field work on the island. Other names reflect the Spanish and Bulgarian exploration and mapping in the area, such as Española Cove, Mount Reina Sofía, San Telmo Island, Ballester Point and Castellvi Peak (after Antonio Ballester and Josefina Castellví, doyens of the Spanish Antarctic programme), Quiroga Ridge, Dañobeitia Crag, Ojeda Beach, Enrique Hill, Sàbat Hill, Casanovas Peak, Bulgarian Beach, Krum Rock (or Krumov Kamak), Pimpirev Beach (after Christo Pimpirev, doyen and leader of the Bulgarian Antarctic programme), Vergilov Ridge, Kuzman Knoll, Dimov Gate, Gurev Gap, Yankov Gap etc. Hespérides Point is named after BIO Hespérides, a Spanish Navy oceanographic vessel serving in particular as a resupply ship for the Spanish and Bulgarian bases for many years. Rongel Point and Las Palmas Cove are also named after modern Antarctic ships. A concentration of place names (probably the highest in Antarctica) arising from local topographic diversity – over fifty names, mostly Chilean, occurs on the small ice-free headland forming the northern extremity of Ioannes Paulus II Peninsula and ending in Cape Shirreff. Scientific bases and camps The first modern, 'post-sealer' habitation facility on Livingston Island was the British base camp Station P that operated during the 1957/58 summer season at South Bay, on the east side of the small ice-free promontory ending in Hannah Point. The scientific bases of Juan Carlos I (Spain) and St. Kliment Ohridski (Bulgaria; often shortened by non-Bulgarians to Ohridski Base, sometimes misspelt as Ohridiski) were established in early 1988 at South Bay, on the northwest coast of Hurd Peninsula. Doctor Guillermo Mann Base (Chile) and adjoining Cape Shirreff Field Station (USA) operate on Cape Shirreff since 1991 and 1996 respectively, while Cámara Base (Argentina) on the tiny nearby Half Moon Island is one of the early bases in the Antarctic Peninsula region established in 1953. These facilities are used also by visiting scientists from various nations; in particular, the Bulgarian base has hosted the first steps in Antarctic research by scientists from countries such as Portugal, Luxembourg, North Macedonia, Mongolia and Turkey. All four bases are permanent settlements, although inhabited only during the summer
