NEXT FIELD TRIP: Sunday, March 3, 2024, Third time's a charm for the GCAS monthly field trip! At 10:00 AM sharp, meet our trip leader, Marilyn Gendron, at the intersection of Hwy 180 and Hwy 61 (City of Rocks turnoff). From there we will caravan 1/2 hour more, turn left onto the Hatch highway (26), and drive 5 miles to turn left again onto Green Leaf Mine Road (a good dirt road, fine for a street car). Here is a video of the road. Drive 10 more miles passing one check dam (at the 9:34 mark on the video), crossing a yellow cattle guard (11:07) and at the second check dam turn left and park (11:44). It is rocky and uphill to the ridge (1/4 mile?) but there is a trail. There are four petroglyph areas with wonderful images. It is exposed on the ridge with no toilet facilities. Wear sturdy shoes, dress in layers, and bring a lunch. As always, carpooling is encouraged. See you there!

2023's Last Field Trip

C-Bar EA1 C-Bar EA7Our last field trip of 2023 happened on December 3 when Kyle Meredith guided about 13 GCAS members to the C-Bar Ranch area of the Burro Mountains. The day was cool, dry, and pleasant - well suited to exploring archaeological sites and features on foot. Kyle reported it was a perfect day, with the group about equally divided between established members and folks fairly new to the GCAS. We're certain everyone enjoyed the trip, judging by the photos Kyle and Eduardo Arguello took of people in action.

C-Bar EA8Kyle provided the two photos shown of pictographs enhanced by dStretch software, and Eduardo shared his group shots. Thanks to both Eduardo and Kyle for their reports!

Volunteers Sought for Rock Art Recording

Ron Barber Stone_Calendar-RBRon Barber, creator of the Stone Calendar Project, has been studying rock art sites throughout the Southwest and Northern Mexico identifying glyphs that mark specific times of the year using unique light and shadow interactions.  He has some survey predictions for glyphs along the Gila Narrows and other southern sites and is looking for volunteers to help in further research.

Anyone who is interested in spending time in the field recording/filming calendar sun light interactions in the region, please contact Ron directly at [email protected] . Here's more of Ron's background:

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.

Back to Back to Back Field Trip Reports - Part I: Spirit Canyon

The summer months find the GCAS all over the place partaking of events aplenty. Our field trips are no exception; by the close of the first week of July we will have enjoyed a total of three field trips in five weeks.

2019-06-02 CO Spirit Canyon field trip IMG_1067On June 2, 2019, the GCAS's very own Marilyn Markel led our monthly field trip to two sites located near each other. Our first stop was to Spirit Canyon in the upper Mimbres Valley area. Spirit Canyon is a unique rock art site monitored under the New Mexico SiteWatch Program. About a half-mile walk up the canyon trail and carefully avoiding the lush growth of poison ivy, our group encountered a series of red ochre pictographs that reportedly depict either Apache Mountain Spirits, or the Apache ceremonial dancers who represented the Mountain Spirits.

GCAS Field Trip to Paquimé, Part II

IMG_423125 - Olla - photographing the cliff face May 2, 2018, the first day of our GCAS international field trip to archaeological and 33 - Yep  Golondrina historic sites in Chihuahua, Mexico, was windy and action-packed. We hiked for about 1/3 mile from La Cueva de la Olla crossing a shallow stream and the valley floor, up a short, steep path to the cave and cliff dwellings of La Cueva de la Golondrina ("Cave of the Swallow"). Occupation of this site has been dated to roughly 1000-1050 CE; somewhat more recent and for a shorter duration than La Cueva de la Olla. (h/t Marcia Corl for far left image.)

One of the structures in La Cueva de la Golondrina (see photo over here on the right) was built in a unique 27 - Golondrina circular cliff dwellingcylindrical shape, yet it and the other more conventional, rectangular-shaped adobe rooms at this site used the same defensive techniques of small ventilation windows and narrow, low, T-shaped doorways that seem typical of cliff dwellings of this era throughout northwest Mexico and southwest US.

31 - Golondrina far L wall's carved steps 32 - Golondrina far L wall porthole detail with lintelsFacing the cave, the cliff dwellings on the far left appeared more intact than those at La Cueva de la Olla; their walls extended all the way to the cave's roof. Slim rows of latillas in the upper parts of small ventilation windows remained in place despite graffiti etched into the surrounding adobe. Steps carved into the sloping rock were still usable to climb up to the cave floor (see photo on far left). The fine sand of the cave floor itself appeared uniformly flat and smooth, even into the cave's furthermost recesses.

Facing the cave along its upper right side, a long panel of white-painted pictographs came into view.
