Footprints, pointing in all directions, of more than forty human beings, together with prints of bison, white-tailed deer, nutria, alligator, and a single-crested guan, occur in lahar and ash at Acahualinca near the cemetery in Managua, Nicaragua, without accompanying artifacts. The haphazard position of these footprints, which are approximately five thousand years old, suggests that the ash fall darkened the atmosphere, adding to the panic and confusion caused by the eruption of one of the cones of the Masaya volcano. Some prints are so deep that they were probably made by human beings bearing heavy burdens.
