Cape Nome is a headland on the Seward Peninsula in the U.S. state of Alaska. It is situated on the northern shore of Norton Sound, 15 miles (24 km) to the east of Nome also on Norton Sound. It is delimited by the Norton Sound to the south, Hastings Creek on the west, a lagoon on the east and an estuary formed by the Flambeau River and the Eldorado River. From the sea shore, Cape Nome extends inland by about 4 miles (6.4 km), connected by road with Nome.
Named Tolstoi ((Russian) "blunt" or "broad") by Mikhail Tebenkov (1833), it was named Sredul ("middle") on an 1852 Russian Hydrographic Service chart, with Tolstoi added as a synonym. The name Nome, used by Henry Kellett in 1849, first appears on British Admiralty charts after the John Franklin search expeditions. In 1901, Sir William Wharton wrote: "The name Cape Nome, which is off the entrance to Norton bay, first appears on our charts from an original of Kellett in 1849. I suppose the town gets its name from the same source, but what that is we have nothing to show." Another interpretation, by the geographer George Davidson, is that a draftsman may have misinterpreted the notation "? Name" as "C. Nome".
Cape Nome is located 129 miles (208 km) to the south east of the Bering Strait. The western extension of the North America and the eastern extension of Asia are separated by the waters of the strait. It is reported that a bridge connected the two parts some years back and that the people of the two regions interacted and trading contacts existed during the start of the Christian era. In 1791 and 1861, Commodore Joseph Billings and Otto van Koztebue carried out explorations close to Cape Nome. A trading post was established at St. Michael along a sea route of 130 miles (210 km) from Cape Nome and by a land route of 225 miles (362 km).
