Skyang Kangri or Staircase Peak, is a high peak of the Baltoro Muztagh, a subrange of the Karakoram range. It lies on the Pakistan-China border, about 7 km northeast of K2, the world’s second-highest mountain. The name “Staircase Peak” refers to the East Ridge, which resembles a giant staircase with five steps. As can be determined from limited exposures, the summit, northern, and northeast slopes of Skyang Kangri consist predominately of limestones of the Shaksgam formation that are largely covered by ice. Further south and west, exposures of K2 Gneiss occur between it and Skyang Luungpa Glacier where the K2 Gneiss is in fault contact with highly folded and faulted strata of the Shaksgam and Baltoro formations.
The lower southeast flank of Skyang Kangri consists of a strip of black slate of the Baltoro formation that underlies the Shaksgam Formation and is in fault contact with main body of K2 Gneiss that comprises K2.
