The precise tektite-hosting stratigraphic horizon has not been specifically delineated as yet but it would be within young Quaternary sediments such as the alluvial terraces of the Belize River. It is also likely that the present-day surface of older limestone terrains located to the north of Bullet Tree Falls and Santa Familia would be identical to the tektite-bearing paleo-erosional surface from 800,000 years ago.
