Quarry Exhibit Hall

Quarry Visitor Center, in Dinosaur National Monument in Utah was built as part of the National Park Service's Mission 66 program of modern architectural design in the US national parks. This visitor center exemplifies the philosophy of locating visitor facilities immediately at the resource being interpreted. The visitor center was closed from 2006 to 2011 due to structural damage from unstable soils. The rotunda structure was demolished and replaced with a new structure of different design, while the quarry section was being stabilized and repaired.
