The British magazine Antiquity has published an article devoted to research conducted by scientists of the Institute of Archeology of the Jagiellonian University (UJ) in Krakow in the canyons on the border between Colorado and Utah in the United States.

The authors of the text are director of the archeological mission Dr Radosław Palonka, Katarzyna Ciomek, Kathleen O’Meara and Zi Xu from the Maryland Institute College of Art in Baltimore.

The Institute of Archeology of the Jagiellonian University has been conducting an archaeological project in the Mesa Verde region located on the border of the states of Colorado and Utah since 2011. These areas are known to both archaeologists and tourists, mainly due to the famous rock cities of the Indians from the pre-Columbian Pueblo culture and thanks to numerous examples of rock art.

This is the first independent Polish archaeological project in the United States and a good example of one of the few European studies in this area.
