to study and appreciate
Specialists in Recording, Conservation, and Management
Stratum Unlimited is dedicated to recording, assessing, analyzing, interpreting, conserving, and managing rock imagery.
Using the latest recording technologies, including drones, GIS, and digital enhancement, the physical condition of sites is assessed, and the identification and quantification of features are documented.
Why Preserving Rock Imagery Matters
Rock imagery, which includes petroglyphs, pictographs, and petroforms, is a physical manifestation of people’s beliefs, traditions, and experiences.
In consultation with all concerned parties, Stratum determines the range of significance of the rock imagery, and then we facilitate the protection of these irreplaceable material remains through careful conservation and management, ensuring their legacy endures for future generations.
