Gabal Hagar El Zarqa (Arabic: جَـبَـل حَـجَـر الـزَّرْقَـاء, romanized: Jabal Ḥajar az-Zarqā’) is the highest point in Bir Tawil, an unclaimed area in the Nubian desert between Egypt and Sudan in Northeast Africa. Due to a long-standing disagreement over the location of that border, its jurisdiction is unclear; it is said by the National Geospatial-Intelligence Agency to be in Egypt. In December 2017, British mountaineer Ginge Fullen accompanied by a local guide summited a point 400 m (1,300 ft) to the east of the waypoint listed on the right, recording a height of 716 m (2,349 ft) at N21 53'01 E33 58'13.
