There's a lake that's a perfect cube - Apparently.
Lake Enriquillo, located in the Dominican Republic, is a saline lake that is almost perfectly cubic in shape, measuring 25 kilometers (15.5 miles) on each side. This unique shape is due to its location in a fault line, where the earth's crust is being pulled apart, creating a depression that has formed into a cube. This phenomenon was first documented by geologists in the 1980s, and has since been confirmed through satellite imaging and field studies.
