The culture focused mainly on agriculture as an occupation, domesticating animals such as cows, bulls, pigs and goats.

Sites around Siswal were excavated by archaeologist Suraj Bhan in different phases revealing an remarkable cultural sequence.

During a three year period from 1967, Bhan was able to excavate ninety seven sites in the area in order to reach conclusions on the Harappan culture.

Upon conducting the small scale excavations, Suraj Bhan was able date a time period ranging from Kalibangan to Late Harappan culture within the region.

Bhan has also noted a clear trend of evolution in typology from the lowest to the upper levels.

This second phase is characterized by the austerity in shape and design, along with a disappearance of painted white pigment.

In accordance to this, Bhan separated non-Harappan sites on presence of a worn out medium thick red ware treated with red slip and painted with black bands, though he admits similar typology and firing with these and Siswal wear.

Lastly the third and final group is characterized by the appearance of medium fabric made through a fast wheel and treated with a red slip in the case of vessels.

Similar pottery is also found at Lohari Ragho, hence treated as a site belonging to Sothi–Siswal culture.
