About the Multiple Ascent Grid:

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

There are 22 interstate highways in the USA with a length of over 600 miles—in order, this is a list of the numbers of these routes:

5, 10, 15, 20, 25, 29, 35, 40, 44, 55, 64, 65, 70, 75, 77, 80, 81, 84, 85, 90, 94, 95

The longest is I-90 at 3020 miles, and the shortest is I-77 at 610 miles. This network of long highways divides the area of the 48 contiguous states into 85 chunks of land, and this list shows the highest peak for each of these sections.

Note that for the purposes of this analysis, interstate highways that approach coastal areas are assumed to continue to the ocean for the purposes of dividing the regions. Also note that some of these areas, particularly near Chicago and Los Angeles, can be very small.

This list includes many high, popular and well-known peaks, including 15 state high points and an additional 53 county high points. Most of the remaining 16 peaks are quite obscure. Overall, it’s an interesting grab-bag of objectives.


Thanks to Ron Tagliapietra, who created this list as a labor of love, and Andy Martin, who helped with the research.
