[Horseshoe Bay] is a U-shaped river of the Colorado River in Arizona. Because the giant rock around the river is like horseshoes, it is called "Horseshoe Bay", although I don't see horseshoes standing on the wall of the canyon that is said to be 300 meters high, overlooking a bay of blue water with a large corner of 270 degrees. Really shocking (a child who is afraid of heights refuses to go near to see 😂).
