Two of Roberts' most sought-after works collected into one volume.

    They set out to attempt the second ascent of the monstrous Koh-i-Krebek (20,500 feet) by a new route from the south; to ascend if possible at least one other major unclimbed mountain and to map that previously unmapped terrain.In fact, as well as Krebek they climbed nine other major peaks, named another dozen, and established the existence of a dramatic rock and ice range which they called the Rum Mountains, and christened individually after the Hebridean peaks they resembled in shape and beauty.The story of the expedition is told with an infectious enthusiasm for the glory and challenge of these mysterious peaks, most of which had been hitherto quite unknown, and there is something akin to the Renaissance spirit of adventure in this exhilarating Scottish expedition of discovery to the roof of Asia.
