Coordinates: 62 ° 11 ′ 0 ″  S , 58 ° 58 ′ 0 ″  W The northwest platform is a 35 to 40 meter high plain in the northwest of the Fildes Peninsula of King George Island , the largest of the South Shetland Islands . To the north of the Central Passage , where it borders the Davies Heights in the east(labeled “Zentralberge” on the German map from 1984), the platform occupies the western half of the peninsula; south of the Gemel Peaks , where it isborderedto the east by the southern mountains , it tapers in a wedge shape to thesouthwest and ends at the Horatiobach at the base of the Flat Top Peninsula . The plain is criss-crossed by shallow valleysand overlookedby individual rock peaks (such as the Gemel Peaks mentioned) and knolls; the mountain ranges are set off from the plain by steep flanks. To the west, towards Drakestrasse , the platform forms a steep coast, which is interrupted by small bays. From northeast to southwest are the sea elephant , granite , whale and Shell Bay , Bothy Bay ( "Seebärenbucht" on the map), Skua- , Biologist and Horatiobucht . The cliffs are preceded by a wide surf platform towered over by individual cliffs.

As part of two German research trips to the Fildes Peninsula in 1981/82 and 1983/84 under the direction of Dietrich Barsch (Geographical Institute of the University of Heidelberg ) and Gerhard Stäblein (Geomorphological Laboratory of the Free University of Berlin ), the platform and numerous others until then unnamed geographic features of the Fildes peninsula and renamed the Scientific Committee on Antarctic research (Scientific Committee on Antarctic research, SCAR) reported.

In their expedition report, the group around Persch and Stäblein interpreted the plain as a raised surf platform and the steep flanks of the mountain ranges as a former cliff coast.
