About the Multiple Ascent Grid:

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

This list shows all marine island high points in Washington State with an elevation of 200 feet or higher. Excluded are all islands in lakes and rivers, such as Mercer Island in Lake Washington or islands in the Columbia River.

Most islands on this list are in the the San Juans archipelago or the convoluted passages of Puget Sound. One is in Willapa Bay in southwest Washington, and two are in the Pacific off Cape Alava.

Climbing all peaks on this list is difficult due to access issues on several islands. Jorgenson Hill is on a Naval Reservation and closed to the general public, and the two islands near Capa Alava are part of a wildlife refuge and off-limits to protect bird nesting sites. Many of the smaller islands in the San Juans have no bridges or ferry service, so kayaking skills might be more important than climbing prowess for many of those peaks.


Thanks to Paul Klenke, who inspired this list and did a great deal of inital research.
