This ridge was climbed by a Polish expedition in 1983 using fixed ropes while making the first ascent of 7,531 m (24,708 ft) Batura V and VI
They ascended the Batura VI peak next door, which I guess happens to be almost as tall as Muchu Chhish (Batura V). Interesting that the wiki article claims they ascended Batura V and VI, but their linked references by the American Alpine club says it was Batura IV. Probably a scrivener’s error, since 7,531 is the height of Batura VI.
