St. Boris Peak (, ) is an ice-covered mountain rising to 1,699 m in Friesland Ridge, Tangra Mountains on Livingston Island in the South Shetland Islands, Antarctica. It is the second highest peak of both the mountains and the island after Mount Friesland (1,700.2 m). The two are connected by a short saddle dominated by ‘The Synagogue’, a sharp-peaked rock-cored ice formation abutting upon St. Boris Peak. The peak is also connected to Simeon Peak by Paril Saddle, and surmounts Huntress Glacier to the northwest and west, and Macy Glacier to the southeast. The peak's central summit is rising to 1,685 m, while its highest point ‘The Synagogue’ rises to 1,699 m. The local ice relief is subject to change; according to a Bulgarian GPS survey by D. Boyanov and N. Petkov the elevation of Mt. Friesland was 1,693 m in December 2016, making St. Boris Peak the summit of both Tangra Mountains and the island in that season. According to the American high accuracy Reference Elevation Model of Antarctica (REMA), Mount Friesland is higher than the central summit of St. Boris Peak and higher than ‘The Synagogue’. The peak was first ascended and GPS surveyed by the Bulgarians D. Boyanov and N. Petkov from Camp Academia area via Mount Friesland on 22 December 2016. A different route was followed by the same climbers and N. Hazarbasanov on 15 January 2017, namely from Nesebar Gap via upper Huntress Glacier and Academia Peak. The feature is named after Czar St. Boris I of Bulgaria, 852-889 AD. Location The central summit of the mountain is located at , which is 650 m south-southwest of Mount Friesland, 4.34 km northwest of Peshev Peak, 1.86 km north-northeast of Simeon Peak, 4.89 km southeast of Willan Nunatak and 3.85 km south-southeast of the summit of Pliska Ridge (Bulgarian topographic survey in 1995/96, and mapping in 1996, 2005 and 2009). St. Boris Peak cultural references The naming of this Antarctic peak after a Bulgarian saint was reminded by the British press in connection with the victory of Boris Johnson in the London mayoral election on 2 May 2008, that particular day being St. Boris's Day in the Bulgarian Orthodox Church.
