Prim Rocks – Arkansas
A “Prim rock” refers to the large, spherical sandstone boulders found in and around Prim, Arkansas. These geological formations are known for their unusual round shape and can range in diameter from about one foot to four feet. Experts believe they are a result of weathering processes that have shaped the sandstone into these distinctive forms. These boulders are not only a natural curiosity but also a part of the local heritage, often seen in fields and forests near Prim. They are a popular subject for photography and a point of interest for both locals and visitors interested in geology and natural history.

Grand Rapids. Athabasca River. Alberta Can.Check out these massive Concretions that have come to surface on the Athabasca River at the historic class VI Grand Rapids. These natural wonders are some of the best examples of spheroid boulders found anywhere in Canada, and perhaps some of the largest on the planet.
