Major Sites and Interaction Networks of the Indus Tradition, Harappan Phase, 2600-1900 BCE, courtesy of J. M. Kenoyer. Six large Indus cities have been discovered. In Pakistan, Harappa was excavated extensively in the 1920-30s', 1960's, and from 1986-2010. Mohenjo Daro was excavated extensively in the 1920-30's, with smaller projects in the 1940's and 1960's. Ganweriwala was discovered in the 1970's and has not been excavated. Lakhanjo Daro was discovered in 1986 but only recent excavations in 2009-2014 have shown that it is probably as big as Mohenjo Daro. In India, Dholavira was excavated in the 1990's and Rakigarhi excavations were begun in the 1990's and resumed in 2013-14.
