Which mountain is taller, Istor-o-Nal or Siguang Ri?
Istor-o-Nal:  It is the 68th highest independent peak in the world. Istor-o-Nal:  Because Istor-o-Nal is behind the higher peak of Tirich Mir from many viewpoints, it is not easily visible and therefore not well known. Siguang Ri:  At an elevation of 7308 m it is the 83rd highest peak on Earth.
