Stratum specializes in mapping, excavating, recording, condition assessing, and making management recommendations for rock art (pictographs and petroglyphs) sites and sites with piled stone features (petroforms). Working in close collaboration with representatives from Indigenous communities whenever possible, Stratum strives to study and present places with rock art and piled stone features within a wider landscape context.
To ensure a better understanding and interpretation of information collected in the field, Stratum co-operates with specialists, such as physicists, chemists, geologists, biologists, ethnographers, and historians. With the input by qualified Geographic Information System specialists, Stratum provides high-resolution three-dimensional models of rock art sites and stone pile features.

Stratum Unlimited does most of its own rock art and archaeological field work, analyses, graphics, and write-ups. However, Stratum also analyzes, synthesizes, writes-up, and illustrates excavated materials supplied by other Cultural Resource Management firms to ensure high quality, informative, and accurate reports.
