    en.wikipedia.org/wiki/Mountain_climbing_problem

    A trivial example. In mathematics, the mountain climbing problem is a mathematical problem that considers a two-dimensional mountain range (represented as a continuous function), and asks whether it is possible for two mountain climbers starting at sea level on the left and right sides of the mountain to meet at the summit, while maintaining equal altitudes at all times.

  3. Grade (climbing) - Wikipedia

    Adam Ondra on the sport climbing route Silence, the hardest free climbing route in the world and the first-ever at 9c (French), 5.15d (American YDS), and XII+ (UIAA)..

    First-free-ascents that set new grade milestones are important events in rock climbing history, and are listed below. While sport climbing has dominated absolute-grade milestones since the mid-1980s (i.e. are now the highest grades), milestones for modern traditional climbing, free solo climbing, onsighted, and flashed ascents, are also listed.

  8. Beta (climbing) - Wikipedia

    en.wikipedia.org/wiki/Beta_(climbing)

    The official climbing guidebooks were the first systematic forms of beta. [10] The beta in these physical climbing guidebooks was limited to the basic details of the climbing route (e.g. length, grade, direction/topo etc.) so as to manage the size of the guidebook and avoid giving so much information that would spoil an onsight attempt. [10]

  9. Exposure (heights) - Wikipedia
