Mamu is a rock hole site about one hour south-west of Pipalyatjara. Alkuwari was travelling with her jamu (grandson) and her grandfather (also called jamu). They made a camp with fire and big wiltja. Alkuwari was worried that her grandson was going to harm her grandfather, and she needed to go hunting. So, she hid her grandfather on top of the wiltja and went. The boy put the waru (fire) inside the wiltja and burned the grandfather. Alkuwari saw the smoke and she ran and ran to the wiltja but the grandfather had died. The jamu had run away so she went and got all her family to follow him, to kill him. They became the mamu and turned into the seven rock holes of Mamu.
