Zavera Snowfield (Bulgarian: Ледник Завера, 64°06′30″S 58°52′00″W / 64.10833°S 58.86667°W) is the glacier extending 18 kilometres (11 mi) in a north-south direction and 16 kilometres (9.9 mi) in an east-west direction on southern Trinity Peninsula in Graham Land, Antarctica. It is located in the northeast foothills of Detroit Plateau, south of Diplock Glacier, north of Mount Wild and northeast of Kopito Ridge. It drains into Prince Gustav Channel in Weddell Sea. The glacier is named after the Bulgarian liberation uprising of ‘Velchova Zavera’ in 1835.[1]
