There's a lake that's a perfect cube
Lake Enriquillo, located in the Dominican Republic, is a saltwater lake that has a cubic shape. Measuring approximately 100 kilometers (62 miles) on each side, it is one of the largest lakes in the Caribbean. This unique shape is due to the lake's position in a depression in the valley, which has been shaped by tectonic activity over millions of years. The lake's volume can vary greatly depending on the amount of rainfall and evaporation, but its cubic shape remains a striking geological feature.
