Uummannaq, Mountain summit in Avannaata, Greenland.

Uummannaq is a 1,170-metre granite and basement gneiss mountain on Uummannaq Island in Uummannaq Fjord. Its base covers the island's entire northern half, and it has two summits of similar height, the eastern being higher, with deep chimneys falling north and south from the col between them. The eastern wall drops as a uniform cliff into Assorput Strait.

The mountain remained isolated and difficult to reach, with only two documented successful climbs recorded before 1992. Access became easier later as better transportation methods made the remote location more reachable.

The name Uummannaq comes from the Greenlandic language and means heart-shaped, reflecting how the mountain's outline appears against the northern sky. This name is deeply tied to local identity and shapes how people perceive and connect with the place.

Reaching the mountain requires boat travel or small aircraft, as no roads lead to this remote Arctic location. Visitors need specialized climbing equipment and should prepare for extreme conditions.

The two summits are joined by a col from which deep chimneys drop to both the south and the north. The southeastern pillar carries several trabant bastions, and black bands run through the southern wall, northeast of that pillar.
