Archeologists find that salt was the secret success in ancient Chaco Canyon

October 2016

According to a study done by researchers from the University of Cincinnati, various salt compounds were found deep in the soil of New Mexico’s ancient Chaco Canyon. These salt compounds, when mixed with the volcanic minerals that were already in the area, are perhaps the secret to the fertile land many years ago. The Ancestral Puebloans collected water runoff from snow and rain for both drinking water and to irrigate their crops. The runoff provided extra minerals for their crops. These are just a few of the innovations that Ancestral Puebloans contributed to the science of agriculture. For more information, please visit
