Nasera Rockshelter hosts a highly continuous sedimentary record, containing a wide array of archaeological remains from Middle Stone Age, Later Stone Age and Pastoralist occupations. Excavated by L. Leakey and M. Mehlman, geological studies carried out by R. Hay included granulometric and general mineralogical analyses but lacked individualized, detailed description and interpretation of each of the 25 levels exposed. This study presents updated detailed geological descriptions and interpretations of 17 levels exposed during excavations in 2018.
