Furthest your city's skyline can be seen from?

It's just one of Toronto's daily sinkings into the lake.

I think Hamilton has a similar ratio.

That's a really interesting hypothesis. I wonder which of those is the main contributor to the effect on that photo, or if there are any others.

Always thought this was a cool picture

Man, that makes Ivor Wynne look like a Div II NCAA stadium in Gary, Indiana.

Jesus, it makes McMahon look nice.

Good call on Gary. The CN could sub for Willis and it'd look exactly the same.

Winnipeg ?? Aprx: 400 km...

haha nice try! I like that. Good idea.

I can see Sherbrooke's skyline from Toronto.

Like the majority of posts in this thread, I don't have a pic to prove it

A visual, just to show you how bad. Red is "urban" (at minimum, rowhouses). Blue is completely, 100%, without exception suburban, single-family detached homes or commercial power centres.

Had to try..

That's true.. you can see downtown from about Av. des Laurentides pretty clearly.


You can also see downtown Ottawa quite clearly from many points in Gatineau Park that are near-total wilderness. These points are generally not as far as Buckingham, however...[/QUOTE]

I've seen Ottawa from the Tenaga/Old Chelsea exit on A-5.. not sure how far that is as the crow flies, but driving it would be about 20 km..

You can see downtown Moncton from the Caledonia Mountain Road, which is 27 km due south of the city.

Nah bro that's photoshopped, the Earth is flat, AINEC.

I do have a photo contribute, from the summit of Moose Mountain. It isn't quite as obvious as the one from Mount Bogart. Might have to zoom/squint a bit.

I don't know if the moon thing is serious or not, but just to clarify, the effect in that Toronto photo is not due to the moon. The moon's effect on water is the tides and there are effectively no tides on the Great Lakes.

It might not be, but it could be a mirage as well? Who knows. It very well could be just the curvature of the planet. I just didn't realize there would be such a major difference over such a short distance.

It has nothing to do with the moon... Tidal effects for Lake Ontario are insignificant. Rather, it has everything to do with the curvature of the earth.

The shot of Toronto from Lake Ontario is not due to a mirage effect either. A mirage is essentially caused by light traveling through air (in a curved line) with a varying index of refraction, which is caused by air that varies in density (lower density results in a reduced index of refraction). Variations in the density of the air over the lake would be caused by air temperature stratification.... but any air temperature stratification would be moderated by the lake rather than exacerbated by it.... I can't see a mirage effect in the photo. What you see is almost entirely due to the curvature of the earth.

The index of refraction of the air is important because it tells us how light will refract though it. If the density/temperature of the air is fairly consistent, the light will travel in a fairly straight line and you will not get a mirage which requires that the light from the distant object of regard curves.


If you want do see a mirage, look over land that is rapidly heating or cooling.
