Horseshoe Island (from English horseshoe 'horseshoe' ) is an approximately 12 km × 10 km island in the northeast of Marguerite Bay , which takes up almost the entire space in the entrance to Square Bay on the Fallières coast in the west of the Antarctic Graham Land. The highest point is Mount Breaker in the southwest of the island, at 879 meters. The island is divided into a smaller northern part with Mount Searle (537 m), which is cut off from the southern part by Gaul Cove in the northeast and Lystad Bay in the southwest. The isthmus is 1,400 meters wide and 90 meters high.
The island was discovered, photographed and mapped by participants in the British Graham Land Expedition (1934–1937) led by the Australian polar explorer John Rymill . Rymill named it based on the crescent-shaped arrangement of its 600 to 900 m high peaks, which give it the appearance of a horseshoe .
In the north of the island was the British Base Y (Margerite Bay, also called Horseshoe Island), which was in operation from October 26, 1957 to 1958 as part of the International Geophysical Year . The station building is protected as a HSM-63 Historic Site .
