Inside the visitor center as of 2001.
The center in 2001 was built into the quarry of Jurassic rock.
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 in 2006 due to structural damage from unstable soils. The rotunda structure is being demolished and replaced with a new structure of different design, while the quarry section is being stabilized and repaired.[4]
