How old are the footprints at White Sands? It depends on who you ask. Scientists are currently divided on this question, but the division is one that is propelling more research with the goal of determining whether humans have been in North America for 23,000 years or closer to 15,000 years.  The ditch weed, or Ruppia, is at the center of this debate. What can a plant tell us about carbon dating to determine the age of the footprints at White Sands? What are the pitfalls of depending on an unreliable organic material? Dr. John Taylor-Montoya, director of the Office of Archaeological Studies, and Dr. David Rachal, a geoarchaeology consultant, have a lot to say about the scientific debate about the age of the footprints—and about the research that needs to be done to resolve the question.  Mentioned in this Episode:  <a href="https://bit.ly/ecdavidrachal">Dr. David Rachal’s White Sands research papers</a> <a href="https://bit.ly/ecdavidrachalyoutube">White Sands field interview with Dr. David Rachal</a> <a href="https://bit.ly/ec0704elpal">History, Science, Mythology, and the First Americans article</a> in Summer 2023 issue of El Palacio <a href="https://bit.ly/ecnmoas">New Mexico Office of Archaeological Studies</a> We’d love to hear from you!
