Robert Mark (Chief Scientist) and Evelyn Billo (CEO) founded Rupestrian CyberServices in 1997 to pursue rock art research, documentation, and education.
While working on a US Geological Survey project around 1980, Evelyn and Robert were asked by the park superintendent to evaluate the geology of the newly discovered solar marker on Fajada Butte. Thus began their enduring interest in rock art studies.
