Kongsbreen ("Kings Glacier") is a complex tidewater glacier draining part of the icefield of Holtedahlfonna, as does Kronebreen. According to the 1:100,000 topographic map, these fast-flowing glaciers were still joined at their termini in 1966. Kongsbreen South has receded over 2 km since then. Kongsbreen has a second tidewater terminus (Kongsbreen North) to the NE of Ossian Sarsfjellet, although recession of both arms along the eastern flank of Ossian Sarsfjellet is so rapid that it is conceivable that this land mass will become an island within a decade.

Kongsbreen’s northern terminus viewed from an area of dead ice. The two areas were connected in the early 1990s, and this wide bay has formed since (JA).
The SE margin of Kongsbreen South, showing heavily crevasse ice, terminal cliff and a scattering of icebergs (JA).
A rare glacier table on dirty stagnant ice below Ossian Sarsfjellet (JA).
The NW margin of Kongsbreen South with unusual medial moraine looping around the side of Ossian Sarsjellet (wide panorama; may require scrolling t o the right; JA).
The terminal cliff provides a good cross section of the medial moraine. It is a discrete inclined debris layer, interpreted as a thrust where ice impinges on Ossian Sarsfjellet (JA).
Associated with the debris-rich moraine-forming layer are a series of parallel structures also interpreted as thrusts (JA).
Close up of thrust, with freshly calved blue ice contrasting strongly with the weathered white ice (JA).
Heavily fractured ice, ice-rubble and a few icebergs characterise this part of the ice cliff (JA).
Ultrawide-angle view from the glacier surface, looking towards Colletthøgda. Large arcuate crevasses form close to the calving front; these show debris-bearing thrusts in cross-section (JA).
View along the length of an arcuate crevasse, illustrating extending flow close to the calving front (JA).
Marble of Proterozoic age, displaying multi-coloured layering that is faulted on a scale of a few centimetres (JA).
The same marble, also showing intensive faulting. The surface has been polished and striated during a previous advance of Knongsbreen (JA).
General view of striated marble surface with a scattering of erratics. Kronebreen South in the background (JA).
