Sentinel Range map.


Sikera Valley (Bulgarian: долина Сикера, ‘Dolina Sikera’ do-li-'na si-'ke-ra) is the 17 km long and 5.7 km wide ice-filled valley between Doyran Heights and Flowers Hills on the east side of Sentinel Range in Ellsworth Mountains, Antarctica. A steep 4-km side glacier draining northeast from Mount Havener in Doyran Heights empties into the upper part of the valley next south of Kostinbrod Pass. The valley ice flows southeastwards towards Rutford Ice Stream.


The feature is named after the medieval fortress of Sikera in southeastern Bulgaria.
