In 2011, the National Park Service and CyArk collaborated to digitally preserve Sivu'ovi, Petrified Forest National Park. The main goals of the project were to document the Sivu'ovi sites and the surrounding landscape and to create a base digital record of Sivu'ovi for use in archaeological research, conservation, education, and tourism. Many of the sites are situated on the edge of the bluff, which creates serious erosion problems. Theft of petrified wood is also a major concern, and nearly 14 tons of the fossil wood disappear from the forest each year. The documentation process included digital photography, terrestrial laser scanning, traditional survey, and HDR panoramic photography.
