Are you sure those co-ordinates are correct ? I see nothing near that height in that area. That Google height you give is 5749m. Google heights are usually WAY off, but there is a peak marked 5827m around those co-ordinates you give, named B21.
On the other side of the Shigar Valley there is 6400m Koser Gunge that is roughly 35 40 N 75 40 E.
