The term MISSISSIPPI SIGHT refers to three distinct features of the Mississippi River. The first is a BARGE, which is a large, flat-bottomed boat used for carrying cargo on rivers and canals. The second is a LEVEE, which is an embankment built to prevent flooding from the river. The third is the DELTA, which is the triangular area at the mouth of the river where it meets the sea. All three of these features are common sights along the Mississippi River.
