Adjacent Islands
Maliy Begichev
Only 8.5 kilometres (5.3 mi) west of Bolshoy Begichev lies the much smaller island known as Maliy Begichev Island. Its size is only 15 square kilometres (5.8 sq mi). The border between administrative divisions of the Russian Federation runs between the two Begichev islands, so that while Maliy Begichev is in Krasnoyarsk Krai, Bolshoy Begichev is in the Sakha republic.
Both Bolshoy Begichev and Maliy Begichev are named after Russian polar explorer Nikifor Begichev.
Preobrazheniya
North of Bolshoy Begichev lies small Preobrazheniya Island. This elongated granitic island was useful as a landmark for ships plying the Northern Sea Route in the past.[1]
