In his book, Canada"s Stonehenge, Freeman postulates that Iniskim Umaapi was part of a vast, open-air sun temple. He believes the stone circle was used as a calendar to mark the changing seasons and phases of the moon. "These discoveries show that genius existed on the North American Plains 5,000 years ago and probably much earlier than that," Freeman wrote. He also described the site as "the most intricate stone ring that remains on the North American Plains".
