About the Multiple Ascent Grid:

  • This table grid shows all peaks on a given list, and all ascents done by Tom Pomeroy, 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

To be on this list, a peak must be the triple divide point of three basins of rivers that reach marine water, and the smallest of these basins must have an area of over 1500 square miles. This last condition excludes what could easily be hundreds of peaks that are triple divides that involve small rivers and tiny coastal creeks.

Also, this list only shows triple divide points for rivers that enter the ocean directly (or for well-defined internal drainages). Therefore, the entire Mississippi-Missouri-Ohio system is considered one basin, and triple divides that include two or three components of this system (e.g. the Colorado-Arkansas-Platte triple divide, where the Arkansas and Platte are both Mississippi tributaries) are not shown. This does leave out a large number of points in the central part of the United States, but most of these points would be low hills in relatively flat country.
