Summary

A portion of Rock Art Panel 11 located along Petroglyph Trail was documented with the Breuckmann SmartScan HE. While there are numerous examples of rock art on the cliff wall that lines Petroglyph trail, this panel was chosen for documentation primarily because of ease of access to the panel and because of the quality and variety of figures and motifs present in the rock art. The panel is somewhat divided by a natural vertical ledge that passes through the middle of the motifs. Documentation with the SmartScan HE captured the majority of the motifs located to the right of the vertical ledge.

Description of Final Datasets for Archive:

Data were initially acquired using OptoCat software. Scan images (jpgs) were exported from OptoCat and processed using Adobe Photoshop. The strong vignette caused by using the projector as the principle light source was removed and all photos were color balanced as best as possible to one another. The new images were added back to the scans in OptoCat. From there, the 26 usable scans were imported into Rapidform XOR using the OptoCat Container (.ctr) format. In Rapidform, the data were merged into a single mesh file containing approximately 50 million polygons. The data were too large for additional mesh post-processing and were reduced 50%. Holes were filled on the reduced mesh. The original scans (prior to image editing), the registered dataset, and the final mesh dataset have been archived.
