Seemingly, this photograph has being doing the rounds for a while (though today is the first time I’ve set eyes on it).
I’ve read that the date on the caption on the image is probably wrong, as Niagara Falls did not freeze in that year — and also that it is unlikely that the water would totally freeze over , no matter how low the temperature drops. But the photograph is meant to be authentic — just wrongly dated. Anyway, who cares — I just like the look of the photograph. I love to look at old images of places which are now well-known landmarks — all that as-it-was-then stuff. I particularly like it when the photograph is of a now well-known building which is in the early stages of construction and it is especially nice when there are some people in the picture (so I can check out what they were wearing).
