Spath Peninsula (-64.35°N -111°W) is an ice-free peninsula,, forming the northeast extremity of Snow Hill Island.[1] Historic Nordenskjold's Hut, Antarctic Historic Site #28, is located on the west coast of the peninsula.[2] The Karlsen Cliffs form the peninsula's northwest coast.[3] Wickens Gully, a water-cut ravine, cuts into clay-rich rocks on the peninsula's east side.[4]
The peninsula has several distinct hills on it. Thyasira Hill is a distinctive hill within a group of smaller hills rising to about tall, south of Nordenskjold's Hut.[5] Tesore Hill rises about high on the east side of the peninsula.[6]
The peninsula and its features were named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1995. The peninsula was named for Leonard Frank Spath (1882–1957), eminent UK paleontologist.[1] The cliffs and gully were named for Anders Karlsen, First Engineer on the Swedish Antarctic Expedition, 1901–04 and Professor Otto Wilckens, eminent German paleontologist, respectively.[3] [4] Thyasira Hill was named because of the abundance of the fossil bivalve mollusk Thyasira townsendi found in this area.[5] Tesore Hill is the English translation of the original Argentine name "Cerro Tesore".[6]
