The two are connected by a short saddle of elevation 1,649 m[1] dominated by ‘The Synagogue’, a sharp-peaked rock-cored ice formation abutting upon the central summit of St. Boris Peak.

Friesland was 1,693 m in December 2016, making St. Boris Peak the summit of both Tangra Mountains and the island in that season.

[1] 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 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.
