Cape Evensen is located below Miller Heights on the Graham Coast of the central Antarctic Peninsula, in the region of Crystal Sound. The IBA qualifies on the basis of the Imperial Shag (Phalacrocorax [atriceps] bransfieldensis) colony present and comprises the ice-free ground ~1 km to the east of Cape Evensen. The IBA is 34 km southeast of IBA Island N of Dodman Island, and 36 km southeast of IBA Armstrong Reef.
Steep slopes rise from the northern coastline to heights of up 750 m at the southern extent of this IBA. Information on the vegetation, soils or geology of the site is not available.
The nearest permanent scientific station is Vernadsky (UKR), which is located 125 km northeast of Cape Evensen and operated year-round.
A colony of ~180 pairs of Imperial Shag was recorded as breeding on north-facing slopes ~1 km east of Cape Evensen alongside colonies of Kelp Gull (Larus dominicanus) and skua (Catharacta sp.) (unpublished data S. Poncet pers. comm. 2005).
