Mary Leakey and other researchers studied the hominin footprints and remains in the volcanically sourced Laetoli area in Northern Tanzania, leaving the geologic framework to R.L. Hay's study in 1987. In collaboration with current paleoanthropological research we present a review of Hay's stratigraphic interpretations. Preliminary results show lateral continuity of distinct units, based on 6 measured sections and GPS mapping within an area of 10 km2. The hominin remains and footprints are placed in this detailed framework.
