This is a huge stone inscription that you see beside the road on the "Rainbow Bridge" right before you enter Canada. It's called the Rainbow Bridge because of what's inscribed here -- it's a quote from the Bible in Genesis 9 and Ezekiel 1. Here's what it says.
From Genesis 9: And God said, This is the token of the covenant which I make between me and you and every living creature that is with you, for perpetual generations: I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth. And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud: And I will remember my covenant, which is between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh. And the bow shall be in the cloud; and I will look upon it, that I may remember the everlasting covenant between God and every living creature of all flesh that is upon the earth.
From Ezekiel 1: As the appearance of the bow that is in the cloud in the day of rain, so was the appearance of the brightness round about. This was the appearance of the likeness of the glory of the LORD.
The last line on the stone is obscured in this photo, but I believe it is from Revelation 4: "There was a rainbow round about the throne."
