Meet D-Stretch: the Archaeologist's Friend

Picto 3 - natural Picto 3 - StretchSome avocational archaeologists have already learned of the fascinating technology of D-Stretch, aka decorrelation stretch, a digital imaging tool that was originally developed to enhance (i.e., "stretch") the color differences in aerial photographs. Today, this technology has become more widely used and user-friendly to boot. It is now an essential tool to analyze rock art images, especially ones too faint for the naked eye to see.

Online Via Zoom: Our November 18, 2020, Featured Speaker, Margaret Berrier

MarglyphWednesday, November 18, 2020, 7:00 PM: GCAS general meeting via Zoom. No business meeting, which means we will begin by welcoming our Featured Speaker, archaeologist Margaret Berrier, who will share with our group "Pisciform Iconography of the Jornada Mogollon," also known as, "Let's Look at Fish: Pisciforms in the Jornada Mogollon Region of Southern New Mexico, Northern Mexico, and West Texas." Margaret points out,

"Numerous examples of fish are depicted on ceramics of the Southwest's ancient Mimbres Culture. These are well illustrated in publications and the Mimbres Pottery Image Digital Database (MimPIDD). However, no significant catalog or publication exists for the Southwest's Jornada Mogollon culture that was partly contemporaneous with the Mimbres. This presentation will include examples of pisciform iconography (fish forms) and their distribution in the Jornada Mogollon area. It also summarizes ethnographic accounts of fish use and interpretation of fish iconography. Included in the presentation will be many examples and comparisons with other archaeological artifacts."
