Rapport Grønlands Geologiske Undersøgelse, 1974 The area discussed here is situated 8 km north of the Sukkertoppen Iskappe and 10 km east of Søndre Strømfjord at 66°27'N, 51°50'W. The work was undertaken during August as part of the programme led by Dr. J. Watterson (see this report). The outcrop of supracrustal metavolcanic rocks is less than 15 km2 in extent.
