Avren Rocks

Avren Rocks (Скали Аврен ska-'li a-'vren) are three adjacent rocks situated in the interior of Micalvi Cove in the south extremity of Robert Island, South Shetland Islands. The group extends 260 m in north–south direction and is 150 m wide. The rocks were first mapped in 2008 by a Bulgarian team. They are named after two settlements in Varna and Kardzhali provinces situated in northeastern and southeastern Bulgaria respectively.
