1875, Below Table Rock in Winter, Niagara Falls

Historic 3D photo (stereograph) adapted for VR. While this image is not numbered and does not mention the year, I am convinced it is 1875 by comparison with another image from the same photographer. See the right hand side of this broader view, which also gives a sense of how the present image was taken from about half way to the top. http://deovr.com/opcaec Fun fact / shameless brag: While I usually just eyeball the perspective to guess the horizon height for eye level, in this case I used the vertical difference from edge to middle of the [staircase-case?] ridges to trigonometry the point where they would be vertically equal (level) based on one ridge at top and one ridge near bottom.
