The Rock Stop at 385 West State Street in Orderville occupies a building shaped to look like a giant rock — a monument to the Utah Septarian Nodule, the fossilized concretion found throughout the Colorado Plateau that became the shop’s signature product. Joe and Maria Caruso founded the rock shop in the 1970s and spent decades building expertise in the Septarian — a form Maria Caruso called "the most beautiful rock in the world." Their son Bob took over and still cuts and polishes the nodules by hand.
In 2008 Don and Mickey Davis purchased the business. In 2022 twin daughters Terri Halstead and Carrie McGuinn acquired it, adding a coffee operation, Rockin’ Tacos, Rockin’ Donuts, and a full-service café alongside the rock specimens and gifts. The building remains a "valley classic" that has drawn geologists, collectors, children, and tourists for forty-five-plus years. Daily hours, 8 AM to 6 PM.
The geographic position on Highway 89 — between Zion and Bryce Canyon — means The Rock Stop captures both the park visitors moving north and the park visitors moving south. The Carusos built something that has survived three ownership changes precisely because the building and the specialty are so specific to this place that they cannot be replicated anywhere else.
