Ilchev Buttress

Ilchev Buttress (Bulgarian: Илчев рид, ‘Ilchev Rid’ \'il-chev 'rid\) is the rocky, partly ice-covered buttress extending 5 km in north-south direction, 2.2 km wide and 1374 m high, forming the northeast extremity of Chiren Heights on Velingrad Peninsula, Graham Coast in Graham Land, Antarctica. It has steep and partly ice-free west, north and east slopes, and surmounts Sohm Glacier to the west, Bilgeri Glacier to the northwest, Byaga Point and Barilari Bay to the northeast, and Weir Glacier to the southeast.

The buttress is named after Ivan Ilchev, rector of Sofia University (2007–2015), for his support for the Bulgarian Antarctic programme.
