Evidence from TU2 (A02-39u2] suggests that this secondary rock oval structure [A03-557] to the south-west of the main Pausa ovals, was perhaps an overflow area. As the test unit was placed at the bottom-most portion of the oval (presumably a corral structure) much of the bone and charcoal that was encountered was perhaps fill that was swept to the lowest point in the corral by animal activity. It appears that during the Early Tiwanaku period the enclosed area was relatively level and charcoal and bone were swept to the bottom of the corral area.
