About the Multiple Ascent Grid:

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

Most of the islands (38 our of 49, or 78%) on this list are in Maine. There are no islands over 150 feet high on the USA Atlantic seaboards south of New York harbor.


Thanks to Dave Covill, who did a great deal of exhaustive data entry to get this list complete.
