Kumi Kipa, unoccupied in the Middle Formative, is colonized and comes to be a significant settlement during the LF1. Sector B has a population index of 647 (11.0 ha). There is little evidence of public architecture, only two small mounds being in evidence. I suggest that Kumi Kipa formed part of a larger site complex including T-271 (Sonaji) and T-322 (Kollin Pata). This group of sites will be referred to as the Santa Rosa group.
