Talmud for Berakhot 9:1
הָרוֹאֶה מָקוֹם שֶׁנַּעֲשׂוּ בוֹ נִסִּים לְיִשְׂרָאֵל, אוֹמֵר בָּרוּךְ שֶׁעָשָׂה נִסִּים לַאֲבוֹתֵינוּ בַּמָּקוֹם הַזֶּה. מָקוֹם שֶׁנֶּעֶקְרָה מִמֶּנּוּ עֲבוֹדָה זָרָה, אוֹמֵר בָּרוּךְ שֶׁעָקַר עֲבוֹדָה זָרָה מֵאַרְצֵנוּ:
If one sees a place where miracles were performed for Israel [such as the place where Israel crossed the Red Sea, the crossing of the valleys of Arnon, the crossing of the Jordan, the stone on which Moses sat when he waged war with Amalek, and the like] he says: "Blessed is He who performed miracles for our forefathers in this place." [Over a miracle performed for the many, such as the aforementioned, all are required to bless; but over a miracle performed for an individual, as when one sees a place where a miracle was performed for him, he must say: "Blessed is He who performed a miracle for me in this place." And his son and grandson must say: "Blessed is He who performed a miracle for my fathers in this place." All of the blessings of the Mishnah require mentioning of "the Name" and "Kingdom," any blessing lacking these not being a blessing.] (If one sees) a place from which idolatry was uprooted, he says: "Blessed is He who uprooted idolatry from our land."
