About the Multiple Ascent Grid:

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

The Canadian Shield is one of the flattest large areas on earth, and Ontario makes up a large chunk of this vast landscape of endless lakes and low hills. This list of the highest summits in Ontario shows that they are mostly in several clusters--northwest of Thunder Bay, a few groups near the northeast shores of Lake Superior, and in the Lady Evelyn-Smoothwater area. Oddly, this last cluster has the fewest summits on this list, but includes the highest.

This list was generated using the Ontario Basic Mapping (OBM) GIS Web Service. I queried the "spot elevation" layer to get all points over 630 meters. There may be closed contours without spot elevations that this procedure would have missed, so this list may not be 100% complete. The vast majority of these summits are not named. If the peak was identified on the list (see link below), I used the name there. Otherwise, a simple "Peak XXXX", where XXX is the elevation, is used for unknown peaks.

Credit must go to Brian Back of who did a lot of research that aided in compiling this list.
