Petroglyph Pláticas presentations continue our mission of providing education about the history and archaeology of Mesa Prieta and the Northern Rio Grande Valley and contextualizing the petroglyphs on Mesa Prieta. Presented on the last Tuesday of each month through October at the Northern Rio Grande National Heritage Center north of Alcalde, the gatherings provide an opportunity for learning as well as socializing.
Created between 1693 and 1730, the Segesser I hide painting portrays a punitive expedition comprising Pueblo Indian and Spanish troops against the Apache Indians. Now on display at the Palace of the Governors, the 18 ft. long bison hide painting is undergoing multispectral imaging to identify materials, changes over time and painting techniques. In order to image the huge architectural mural that is Segesser I, a computer controlled travelling imaging gantry table was designed and built. Called the “Franken-Camera”, it allows the painting to be imaged flat and with .001” positioning accuracy. It will take 3817 images to complete this project and create files totally more than 4 Terrabytes.
