Q. See question above. Does the same apply to seeing the Lake Ontario and the rivers close to Niagara Falls?
A. On question 3288 regarding Brocho does one say if any when seeing first time Niagara Falls, we wrote:
“Horav Shlomo Miller’s Shlit’a opinion is than one can recite ‘Ose Maase Bereishis.’ However, if one has recited that blessing within thirty days, as in the case of seeing the sea, one should not repeat it with Hashem’s name.”
Rabbi A. Bartfeld as advised by Horav Shlomo Miller and Horav Aharon Miller Shlit’a
