Land that now belongs to the Petrified Forest National Park in Arizona may have been the site of bustling communities around 1,300 years ago. 

Archaeologists working in the park have unearthed a second ancient village less than a kilometer away from one that was discovered last summer, The Christian Science Monitor reported. The newfound village, which was discovered in July, may have contained up to 75 individual homes inhabited by ancient Pueblo peoples.

“Finding smaller sites is pretty common but to find these larger sites with 50 to 75 structures is more unique,” park archaeologist Bill Reitze told the Monitor. “That’s what makes it interesting and there are some really interesting things to learn.”
