- 49th Parallel FunFacts
The 49th parallel portion of theUS/Canada boundary is marked by 1039 monuments and crosses the 49th parallel 15 times, at locations between the following

Which datum? Just kidding!! :)

Brian, Any opinion as to why Monument 490 is as accurate as it is with respect to latitude? I assume that monumentation of the 49th is as varied as it is due

Also...#490 appears to be approximately midway between Lake of the Woods and the Pacific. Coincidence? I think not! (Just kidding...) ... From: Bill

Jones, Boundary-making , Carnegie endowment, 1945. fig.24 on p154 maps pillars 46 to 58. The bundary is the mean astronomic parallel . it does not coincide

I imagine it s just statistical. Out of 1039 monuments, one of them was bound to be on the boundary. I think the precise positions listed were determined

Interesting thought, but no reason to think the variance would be sinusoidal if it s due to gravitational anomalies. It would be proportional to the square

they are all bound to be on the boundary btw i was seeing things too to think they werent in decimal seconds offcourse they were but bills theory can be tested

I should have said bound to be on the hypothetical boundary and of course you re right, once the markers were set they defined the boundary. ... times,

You re right. My program reported crossings and zeros by comparing adjacent monuments only. I didn t think about the significance of the zero as a
