Blue Headed Vireo

Ongal Peak (Bulgarian: връх Онгъл, romanized: vrah Ongal, IPA: [ˈvrɤx ˈɔŋɡɐɫ]) is a sharp glaciated peak rising to 1151 m^[1] on Levski Ridge of Tangra Mountains, Livingston Island in the South Shetland Islands, Antarctica. It surmounts Shipka Valley on the north-northwest, and Huron Glacier and its tributaries on the north and northeast.^[2]

The peak was first ascended and surveyed on 21 December 2004 by the Bulgarian Lyubomir Ivanov from Camp Academia. It was named after the historic Ongal region of the First Bulgarian Empire located in the Danube Delta area and north of the Black Sea, in connection with the Battle of Ongal.

Ongal Peak is located 520 m north of Levski Peak, 1.76 km southeast of Zograf Peak, 650 m south of Komini Peak, 1.19 km south of Ravda Peak and 2.44 km west-southwest of Plana Peak. Bulgarian topographic survey Tangra 2004/05, and mapping in 2005, 2009, 2017 and 2023.
