About the Snapshot Year-Month Grid

General Considerations:

  • "-X" after a peak name means an unsuccessful ascent, for example "Rainier-X".
  • A parenthetical name is a non-summit goal hike, for example, "(Snow Lake Hike)" or "(Rainier)".
  • The Δ triangle symbol is a hyperlink to the detailed Ascent Page for that ascent. The peak name is a link to the Peak Page for that peak.
  • The color of the cell shows how high, prominent, isolated, or high-quality the peak/ascent is, and the color ranges are shown in the legend to the left.
  • If the color is based on altitude, prominence, or vertical gain, you can switch between meters-based ranges or feet-based ranges. These are set up to be generally equivalent.

This grid comes in seven "flavors", each one showing a different "top" peak for a month. The flavors or categories are:

  1. Highest Point Reached. Can be an unsucessful attempt or non-summit goal hike.
  2. Highest Peak Climbed. Sometimes not the same as highest point, if that point was an unsuccessful ascent or a non-summit goal hike.
  3. Most Prominent Peak climbed. Note that many peaks in the database do not yet have a prominence value.
  4. Most Isolated Peak climbed. Isolation values may not be 100% accurate, since most are cacluated to nearest higher peak in the database.
  5. Peak with most vertical gain hiked. Note that many climbers do not enter vertical gain information on their ascents. Also, if several summits are grouped in a "trip", then the total gain for all ascents in that trip is assigned to the trip high point.
  6. Peak with the highest "Quality" value--this is a subjective number from 1-10 given by the climber. Note that many climbers have not given any of their ascents quality numbers.
  7. Finally, "Top Ascents in All Categories", which shows, for each month, the unique peaks from all the 6 other categories. In many cases, one or two peaks will be the leader in the 6 categories, since often the highest peak climbed for a month is also the highest point reached, the most prominent peak, and the one with the most gain. But in some cases several peaks may appear for a month.
