Noteworthy for its vertical rise, one of highest in Ontario. 2.4 km SW of Griffin L Peak.

Key

 

Peak

The point of elevation as named on either provincial Ontario Base Maps or federal National Topographic Series maps. If it contains "peak" in the name, then there is no map designation, so a nearby waterway or water body was used to identify (the exceptions are Nailhead L and Marne Peak).

Height

Spot height above sea level. In the metre column, any height measure ending in a 0 (multiple of 10) represents the highest OBM contour. All other measures are spot heights on the OBM. For Ishpatina, used measure on National Atlas website .

Vertical Rise

Imagine you were building a ski resort and wanted the longest run to the lowest elevation. You would start at the highest elevation and end at the lowest. Comparing these two points gives some sense of its vertical majesty if you were looking at it from a distance.

This is measured in metres above the lowest nearby water body or waterway, using its OBM surface elevation. If there is a water body or waterway in the name along with the term peak, this water is the foot for the measure. There were two exceptions for those using the peak designation: Nailhead L. where Parch Cr was used; and Marne Peak where the township was used.

    *  Corrected from previous listing on Ottertooth of 2274. During compilation, 693 metres was converted into feet, which rounds to 2274. Subsequent research found that in 1974 Ontario originally published the more precise height of 2275 feet, which also converts to 693 metres.

Criteria  For Listing

1. A minimum of a 50-metre vertical drop occurs somewhere between peak and its nearest higher peak on this list. Measured from the lowest elevation between the two peaks (sometimes called a saddle or col) to lowest peak. This is a form of prominence.

2. One of the highest 25 elevations in Ontario.

Criteria for Height Selection

High elevations were sought on the OBMs and NTS series maps. Some peaks had different elevations between the two series. Additional high-point information was sought in government records, but these did not always agree or state how they were taken or to what level of accuracy.

The newest, most precise elevation measure is the 1:20,000-scale Ontario Base Maps (OBM) series produced by Ontario's Ministry of Natural Resources and covers. The 10-metre contour interval is the smallest of any topographic map. A bonus of these maps is the extensive set of spot heights for which the ministry reports a vertical accuracy of 2.5 metres. Contour interval accuracy is 5 metres.

For consistency and precision, all height measurements were taken from the OBMs.

Height was determined by the top spot height. In the absence of a spot height, the top contour measure was used. Exception was Ishpatina where specific measure was listed on National Atlas website as no spot height on OBM.

Notes

Weakness

If there is a weakness in this list, it is the original long-list selection of peaks. This was done by manually searching all topographic maps for any elevations at or above 630 metres (from which the short list was produced). This search was done by Paul Harker of Natural Resources Canada and Brian Back of Ottertooth.com. This is painstakingly challenging, and some may have been overlooked. Other lists, that could be found, were then searched for additional peaks (though none found). Greg Slayden of Peakbagger.com provided a list of OBM spot heights above 630 metres produced from a search of the OBM database.

The Vertical Rise could vary depending upon which bottom elevation was chosen. The lowest base for peak or ridge was sought, but there was no ideal criteria for determining it.
