The Story of Oregon's Mysterious 25 Mile Wide Circle

Within central Oregon south of the city of Bend is a massive 25 mile wide vast circular structure which easily stands out from the surrounding landscape. So, what exactly is this structure? Is it an impact crater, a buried caldera, or is it something else? Today's video will answer this question and discuss the formation of this large geologic structure.
