What happened to the cities of mohenjo-daro and harappa

Mohenjo Daro or “Mound of the Dead” is an ancient Indus Valley Civilization city that flourished between 2600 and 1900 BC. It was one of the first world and ancient Indian cities. Mohenjo-daro is located in the Sindh province on a Pleistocene ridge in the middle of the flood plain of the Indus River. The ridge is now buried by the flooding of the plains, but was prominent during the time of the Indus Valley Civilization. The ridge allowed the city to stand out above the surrounding plain and be elevated. Mohenjo-daro was discovered in 1922 by R. D. Banerji, an officer of the Archaeological Survey of India, two years after major excavations had begun at Harappa, some 590 km to the north. Large-scale excavations were carried out at the site under the direction of John Marshall, K. N. Dikshit, Ernest Mackay, and many other directors through the 1930s.
