Reading the recent Ottertooth article on the highest points in Ontario leads to a few questions.
Does anyone know if a survey has ever been done of Ishpatina Ridge?
Personally, Ishpatina North looks taller or as tall to me as the south peak (the fire tower is on the south peak).
Does anyone else think the difference between the two peaks looks a lot closer than 13 metres? |

Let me add this interesting photo to Dan's comments, but point out that I am not suggesting the North Peak maybe higher than the maps indicate.
The arrows indicate the two peaks with south on left. You can see the full photo taken by Andy Stevens at

Perhaps the north peak is closer in the photo? |

JohnV: You are right, it is impossible to determine relative distance and height from oblique angle photos. Perspective, and the pitch and yaw of the aircraft can affect perception.
As a note of clarification, when I say that Ishpatina North looks taller, I mean it looked taller when I was there in October 2005.
Actually, I tried to make some measurements using the clinometer on my compass and a home-made level, but my view of Ishpatina North was obscured. Ishpatina North is covered with trees, for the most part, so it is not possible to determine what is actually the highest point.

What about an altimeter? My friend has one on his wrist watch which we used while in the Rockies. This would solve any confusion. Having used one I know they are not totally accurate. But we did notice that the inaccuracies were consistent so it would work for comparing the two altitudes on the ridge. Of course that means you have to climb both points.... not such a bad idea, that....

I used a Paulin Altimeter in school, and like you, wasn't impressed with the results, although as you say, it did seem to show changes in relative elevation .
It would probably take at least two hours to get from the south knob to the north knob, thus increasing the chance for error (based on changing weather, daytime heating).
Since I just want to know which point is higher, it may be more effective to climb Ishpatina North and sight across to Ishpatina South, using some sort of level. I am thinking about doing this in the summer or fall.
I'm surprised that it seems that there has never been a detailed survey of this "highest peak in Ontario". In the northeastern US, almost every hill seems to have a benchmark on top of it. |

Who would want to bushwhack all that brass through all that underbrush while beating off all those mosquitoes and blackflies? |

Here is a question re the article "Indepth Ishpatina". The article states that there are no higher peaks for 1600kms N, 525kms S, 380kms E and 1430kms W. I assume that the highest peaks to the west are the Rockies in Alberta, or perhaps the Cypress Hills in Saskatchewan? Does anyone have some more specific info on these areas in the four directions from Ishpatina? |
