This island is 52.5 km (32.6 mi) in length but only 1 km (0.62 mi) wide on average. It is a long extended bar or spit between the Chukchi Sea and the lagoons of Amguema (Амгуэма) and Tynkergynpil'gyn (Тынкэргынпильгын), coastal lakes which are frozen most of the year.

The island is named after pilot Carl Ben Eielson and mechanic Earl Borland who crashed near it in 1929.^{[citation needed]}

The southeastern section of this island is also known as "Ostrov Dalstroy" after the Soviet organization Dalstroy^{[unreliable source?]}.
