Preservation of Human Tracks in Arid Environments. Lockley, M. G. & Rodríguez-de la Rosa, R. A. Ichnos, 16(1-2):98–102, January, 2009.

Paper doi abstract bibtex Observations were made on the preservation of modern human tracks in a salina near Cuatro Cienegas, Coahuila, Mexico. Track making potential is relatively high in such arid, ephemeral lake basin settings where salinas or alkali flats typically develop. However, because of the instability of evaporite minerals, long-term preservation potential of such tracks is compromised. The substrate in the study area is composed of a mixture of sand and a high percentage of sulfate crystals (gypsum, bloedite, epsomite). At the sediment-air interface, there is a thin white, crystalline sulfate crust that overlies the original track-bearing surface and prevents water loss. The size and surface growth of sulfate crystals in the crust is affected by the differential pressure caused by the track maker. Such tracks represent a good example of a biogenic process (track formation) affecting a physical sedimentological process.
