From the paper Walking in mud: Remarkable Pleistocene human trackways from White Sands National Park (New Mexico) [1]:
> We describe a long prehistoric human trackway (1.5 km) of Late Pleistocene age at White Sands National Park (New Mexico, USA).
> The trackway indicates two journeys. The outbound tracks are crosscut by giant ground sloth and Columbian Mammoth tracks.
> The precise geochronology of the tracks remains uncertain... The most parsimonious interpretation of this window is that track formation occurred before 10 k BP, however the upper biostratigraphic limit depends on the arrival date for human colonisers in the Americas and more specifically at WHSA [White Sands].
