[4] Just south of Trost Peak there is a long, flat ridge where many lichens are present, notably patches of Omphalodiscus decussatus more than 1 metre (3 ft 3 in) across.

The moss Coscinodon lawianus is also abundant on the ridge, the furthest point from the sea recorded for this species.

The northern peak has no lichen but the southern one has many species, including abundant Rhizocarpon flavum and Caloplaca elegans var.

Biatorella antarctica is abundant on Mount Burnett but there are low numbers of Caloplaca elegans var.

This southern range was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936-37, and named Sörkammen (the south comb or crest).

Peak, 980 metres (3,220 ft), standing 1.5 miles (2.4 km) northeast of Mount Burnett in the Masson Range of the Framnes Mountains.

Mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936-37, and named Horntind (horn peak).
