Dagger Interactive Model
THE SOLSTICE PROJECT
The Solstice Project is proud to announce a breakthrough Interactive Computer Graphics Model of the Sun Dagger Site in Chaco Canyon, an astronomical site of the ancestral Pueblo Indian culture. Representing 20 years of research and three years in production, the model is an archival restoration of a thousand year old calendrical site that marks the solar and lunar cycles. The model’s interactive tools offer opportunities to analyze the astronomical functioning of the site and to explore how it was originally developed.
At the Sun Dagger site, the Chacoan people commemorated the cycles of
the sun and the moon in light patterns cast by rock slabs onto spiral
rock carvings. Through state of the art technologies and with an outstanding
team of photogrammatrists, a geodecist and computer modelers, the Solstice
Project achieved its goal of archival digital restoration of the site.
(In 1989, the Project found that the rock slabs had shifted and the light
markings on the petroglyphs had been significantly disturbed.)
The scholars behind the making of the Sun Dagger model over many years include:
Anna Sofaer, president of the Solstice Project has coordinated since 1978 the Project’s interdisciplinary astronomical research and preservation efforts with the Sun Dagger site. Their work included ongoing mapping and surveying efforts since 1979 to record the fragile slabs and spirals, as well as extensive photo documentation of the site’s solar and lunar markings. These efforts finally culminated in the precise digital restoration of the Sun Dagger in 2006.
Phillip Tuwalststiwa, a geodecist and member of the Hopi Tribe, gave his early support and participation in the model building at the Center for Mapping of Ohio State University.
James Holmlund, president of Western Mapping developed the laser-scanned model of the Sun Dagger site in 2006.
Piscitello, president of Aero-Metric Company, developed the 1984
photogametric model of the Sun Dagger site in 2006.
