Photographer's Note

This pic shows 2 of the 3 waterfalls of Niagara. there is an estimation about teh quantity of water flowing: 60 tonnes/minute of dissolved salts and "rock flour" (very finely ground rock) generated by the erosion of the Niagara River itself. The erosion progess is approximately 0.91 m per year.

Avisiting time of 3 -4 hours is sufficient. In the evening it's Vegas...
