Isunngua, Highland in Qeqqata, Greenland

Isunngua is a highland in the Qeqqata municipality of central-western Greenland, not a glacier, lying immediately west of the Greenland Ice Sheet edge. It is bounded by the Isunnguata Sermia glacier to the north, the Russell Glacier and Aajuitsup Tasia lake to the south, and the Sanningasoq twin lake to the west. Its hills average about 500–530 m, and the land is dotted with freshwater lakes, kettles and meltwater lakes saturated with glacial silt.

In the spring of 2000 Skanska's Greenlandic subsidiary finished six months of work on a 30 km gravel road for the Swedish testing company Nausta, running from Kangerlussuaq through the Akuliarusiarsuup Kuua valley to the ice sheet edge in Isunngua. Cars were flown to Kangerlussuaq and driven to the proving grounds to test cold and near-zero friction. The project was abandoned, and since 2006 the road has been maintained for tourists only.

Isunngua is a calving site for reindeer, and the name is the old spelling Isúngua in Danish sources. The gravel road through the highland is used by tourists heading to the ice sheet edge; few hikers walk the route or explore the neighbouring glaciers.

Access requires a key for the padlocked gate along the gravel road starting from Kangerlussuaq. Visitors should bring sturdy vehicles and appropriate gear for the harsh and changeable weather conditions.

The 30 km gravel road built by Skanska's Greenlandic subsidiary for the testing firm Nausta in 2000 once continued 150 km onto the inland ice. Ice activity has since destroyed that inland segment, so the road now ends in Isunngua at the ice sheet edge, and the last stretch is behind a padlocked gate.
