Full list of words from this list:

  1. innocuous
    not injurious to physical or mental health
    To my oxygen-depleted mind, the clouds drifting up the grand valley of ice known as the Western Cwm looked innocuous, wispy, insubstantial.
  2. serrated
    notched like a saw with teeth pointing toward the apex
    Negotiating the serrated ridge presents no great technical hurdles, but the route is dread­fully exposed.
  3. rappel
    lower oneself with a rope coiled around the body from a mountainside
    As I clipped into a fixed rope and prepared to rappel over the lip, I was greeted with an alarming sight.
  4. squander
    spend thoughtlessly; throw away
    I’d just squandered the last of my gas going nowhere.
  5. accretion
    an increase by natural growth or addition
    The actual particulars of the event are unclear, obscured by the accretion of myth.
  6. theodolite
    a surveying instrument for measuring angles
    Designated Peak XV by sur­veyors in the field who’d first measured the angle of its rise with a twenty-four-inch theodolite three years earlier, the mountain in question jutted from the spine of the Himalaya in the forbidden kingdom of Nepal.
  7. escarpment
    a long steep slope at the edge of a plateau or ridge
    To the surveyors who shot it, all but the summit nub of Peak XV was obscured by various high escarpments in the foreground, several of which gave the illusion of being much greater in stature.
  8. mellifluous
    pleasing to the ear
    As it happened, Tibetans who lived to the north of the great mountain already had a more mellifluous name for it, Jomolungma, which translates to “goddess, mother of the world,” and Nepalis who resided to the south reportedly called the peak Deva-dhunga, “Seat of God.”
  9. arduous
    characterized by effort to the point of exhaustion
    The first Everesters were obliged to trek 400 arduous miles from Darjeeling across the Tibetan plateau simply to reach the foot of the mountain.
  10. inextricably
    in a manner incapable of being disentangled or untied
    Mallory, whose name is inextricably linked to Everest, was the driving force behind the first three expeditions to the peak.
  11. expeditiously
    with efficiency; in an efficient manner
    At 12:50 P.M., the clouds parted momentarily, and teammate Noel Odell caught a brief but clear glimpse of Mallory and Irvine high on the peak, approximately five hours behind schedule but “moving deliberately and expeditiously” toward the top.
  12. tenuously
    in a weak, uncertain, or insubstantial manner
    On May 28, following two and a half months of prodigious effort, a high camp was dug tenuously into the Southeast Ridge at 27,900 feet.
  13. bivouac
    a site where people can pitch a tent
    Hornbein and Unsoeld arrived on the summit at 6:15 P.M., just as the sun was setting, and were forced to spend the night in the open above 28,000 feet — at the time, the highest bivouac in history.
  14. proliferation
    a rapid increase in number
    Even before the calamitous outcome of the 1996 premonsoon climbing season, the proliferation of commercial expeditions over the past decade was a touchy issue.
  15. frangible
    capable of being broken
    Near the southern tip of South America, where the wind sweeps the land like “the broom of God”—“la escoba de Dios,” as the locals say—I’d scaled a frightening, mile-high spike of vertical and overhanging granite called Cerro Torre; buffeted by hundred-knot winds, plastered with frangible atmospheric rime, it was once (though no longer) thought to be the world’s hardest mountain.
