"I don't consider it a pause," Christo said. "It's part of the dynamics of the project."
During the work on Over the River, he also is actively working on The Mastaba, a giant sculpture of 410,000 barrels planned for Abu Dhabi that he conceived in 1977. Because he is 77, Christo said he is trying to complete both projects simultaneously rather than focusing on one at a time.
Christo was in Denver for an exhibit Wednesday at Metropolitan State University of Denver's Center for Visual Art of two sketches he donated to Colorado.
