The two large mounds and the bwogero are the major earthworks at Ntusi. The mounds, named the male mound (Ntusi IV) and the female mound (Ntusi III), are both approximately forty meters in diameter with a depth of deposition measuring 4 meters. Excavations at the female mound revealed the mound had been used as a refuse dump for a significant period. Excavators uncovered broken grindstones, pottery, cattle bones, carbonized sorghum seeds, and other household refuse. The surface of the mound received period burnings in order to reduce pests and foul odors of rotting refuse.
Radiocarbon dates for the mound are from the eleventh to the thirteenth century AD. Local agriculture has slowly encroached on the mound and leveled off its surfaces, so much so, that on the southwestern side the mound appears rise very little. Ntusi male mound excavations in 1988 showed that the buildup of the mound was more complicated than the 1921 Wayland and Ntusi III excavations had indicated. The excavated material remains were similar to those in the female mound, but in addition to the household debris, ornamental goods were recovered as well. The upper layers of the mound revealed carved ivory,
ostrich eggshell beads, glass beads, and copper trade goods. Radiocarbon testing has dated the Male Mound to be contemporaneous with the Female Mound. In addition to the main mounds, many smaller mounds (approximately one meter high) are found throughout the site particularly in the area north of the bwogero. ==Bwogero==
