About the Multiple Ascent Grid:

  • This table grid shows all peaks on a given list, and all ascents done by Rob Woodall, up to 10 ascents per peak.
  • While many peakbaggers do not like to repeat ascents, some will try to do multiple "laps" or "rounds" of a favorite list, often one close to home.
  • The header for each ascent column shows, in parentheses, the total number of peaks climbed in each "round", and clicking the header link will sort your ascents for that round.
  • Due to space limitations, this listing has just the basic peak info, so up to ten date columns can be shown. Please use the main peak list (linked above) for more basic info and functionality.
  • Some climbers will log two ascents of the same peak on the same day--for example, when doing an out-and-back ridge run with other ascents sandwiched between two of the same peak. Some might not consider these to be two separate ascents for the purposes of doing multiple rounds. Clicking on the "Count a peak only once per day" link in the header will collapse multiple ascents of a peak on a single day into just one ascent for this grid list.

List Description

By this reckoning, there are only two summits in the world where water drains into three different oceans. Both are glacial ice caps--one in Antarctica, and one in the Canadian Rockies. The exact position where the ice moves in three different directions at these points will shift over time, so neither peak offers a satisfyingly exact mathematical point.

Some geographers subscribe to the notion of a "Southern Ocean", defined as all waters south of 60 degrees south latitude. Those who accept this notion will have to leave Dome Argus off this list, since all ice in Antarctica then flows into one ocean. However, even though the Southen Ocean may have some real-world boundary in the form of the fluctuating Antarctic Convergence water boundary, my feeling is that oceans should be defined exclusively by landmasses that surround them. Therefore, this site does not recognize the Southen Ocean.

Another controversy is whether or not Hudson Bay is part of the Atlantic or Arctic oceans. Good arguments can be made either way, but, to me, the wide Hudson Strait leads directly to the Labrador Sea and the Atlantic. The path from Hudson Bay to the open Arctic is a convoluted route though many islands, so here the South Slope of the Snow Dome becomes the triple-ocean point of North America. But if you consider the Hudson Bay as part of the Arctic, the "Honorable Mention" of Triple Divide Peak becomes the hydrographic apex of the continent.

A final note: there are no triple-ocean points in Asia becasue of vast areas of internal basins that do not drain to the sea in Central Asia. The basins of the Arctic, Atlantic, Indian, and Pacific all end at this large internal area before they can meet.
