This ancient ruin is believed to have been built by the Pueblo people around 1200 CE, making it over 800 years old. The ruin is a testament to their advanced architectural skills and provides a glimpse into the lives of the people who once inhabited this area.

The Standing Cow Ruin is an excellent destination for history buffs and those interested in Native American culture. Visitors can explore the well-preserved ruins and learn about the Pueblo people who once lived there.
