Khardung La is widely, but incorrectly, believed to be the world's highest motorable pass. There are higher motorable passes at Suge La, west of Lhasa, 5,430 m (17,815 feet), and Semo La 5,565 m (18,258 feet), between Raka and Coqen in Central Tibet. Both these elevations are supported by GPS and SRTM evidence and the latter was also measured by the Catalans and supported by the CIC, see above. Information about a 5,590 m (18,340 feet) pass Marsimik La, in the Indian Karakoram to the North-east of Khardung La, can be found here. It is stated that a sign reads "5590 metres, 18634 feet". The elevation given in metres is consistent with SRTM but the elevation in feet, which is equivalent to 5680 metres, is not. It is debatable whether this pass should be considered to be motorable. There may be higher motorable passes elsewhere in Tibet, but verification of these has not been possible because of lack of information and restricted access.
