NEXT MEETING: Wednesday, May 15, 2024, 6:00 PM: our monthly meeting shifts to the Roundup Lodge in San Lorenzo (Mimbres Valley) for the summer months. Doors open at 6PM for a potluck dinner so bring your own plates, utensils, and a dish for yourself or to share with the group. Brief GCAS business meeting begins at 6:30 PM followed immediately by our evening's Featured Speaker, Preservation Anthropologist Aaron Wright PhD, who will present Indigenous Rock Imagery of the Sonoran Desert. Members and non-members alike are welcome to join us for an evening of good food and an engaging discussion. In order to offer our members a safe and comfortable experience at our in-person meetings the GCAS recommends each attendee take the masking, distancing, and vaccination precautions they feel are appropriate for themselves in group gatherings.

NEXT FIELD TRIP: Sunday, May 5, 2024: we aim for an unnamed Mimbres site on Fort Bayard/USFS land. Meet our trip leader, the GCAS's own Torie Grass, at the Big Tree parking lot (USFS directions are here), about a half hour's drive from Silver City. The group will start from the trailhead at 10AM sharp for a hike of about a mile one-way, north past the USFS Hot Shot buildings. The trail is mostly flat, with an incline up to a ridge at the end to reach the site. Torie advises to bring water and a lunch if desired, and to dress with appropriate pants for walking through some dry, stickery brush. Let's go!

Pat Gilman describes her excavationCurrent GCAS member and supporter, and past member of the Mimbres Foundation, archaeologist Pat Gilman announces that the Arizona Archaeological and Historical Society is in the preliminary stages of planning a field trip to the Mimbres Valley from Friday, March 10, through Sunday, March 12, 2023. They've booked a room at the Little Toad Creek Brewery for Friday dinner (March 10), hoping that they can also use the room for a brief Powerpoint overview of Mimbres archaeology presented by Pat Gilman herself.

AAHS is inviting GCAS members to join them for the March 10 dinner - dutch treat - and then join them for any or all parts of the weekend tour they have in mind. Pat reminds us that the AAHS is still in the early planning stages for this field trip, but she asks GCAS members to “Please let me know if you can join us for dinner and the show*.  The Little Toad Creek Brewery would like to know about how many people will be at dinner.  I don’t need to know if you will join us for any parts of the field trip itself, but I hope you can.  I want to show off what you all have done, and I’d like you to talk about it. And I’d like our members to be able to chat with you all who know so much about the local archaeology and the valley.”

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.
