Johns Valley Chert. Still trying to figure out the best way to visualize it for publication. So, I welcome any feedback.

As part of my new position at ATU, I am directing the Center for Heritage and Culture.
The webpage will be for the public. I want to include info about research projects (broader topics) & highlight student projects (conference presentations, etc.).
What else can I share on there?

This was found during one of my stone sourcing field studies. It's a mix of Potato Hills Chert & quartzite/silicified sandstone. Examining artifacts as part of my diss, I have found one biface with a mix of chert & quartzite. The stem was quartzite while the blade was chert.

1/ These pics may not seem like a big deal but it is in my research area.
XRF results of two different raw material (stone) types that have been difficult to distinguish. These results were repeated on different specimens each examined 3 times. This can be repeated to address-

Working on a chapter of my diss. An extensive part of it is about stone sourcing - including pXRF and tracing fluvial deposits to see where & how cobbles are being transported. This goes in distinguishing between if some were traded or locally available.

Now that it's official, I want to share that I have accepted an Assistant Professor position at Arkansas Tech University. I'm looking forward to preparing students for careers in CRM and directing the Center for Heritage and Culture to continue my research in the southeast.

The field school excavations at Spiro have come to an end. I wasn't able to excavate this year, but was able to visit several times and do some artifact identification. These are some photos from the field school but you can check out more at: www.facebook.com/share/16QWWF...

There is a bird nest on the porch. This little one fell and was hiding behind a box that got delivered today. They are fine and back in the nest now.

Wood charcoal (and matrix) from the site I excavated as part of my dissertation. Unfortunately, due to the situation with federal grants, I won't be able to get it dated.

Conducted some fieldwork today. Goal was to determine the level of disturbance (from looting) at the boundaries of the site. Recovered a lot of debitage and a biface fragment - based on fracture it was damaged during biface reduction.

Here is an example of Potato Hills Chert. This high-quality material with vibrant colors has a very limited source range. This material isn't highly traded, but instead seems restricted to groups in a particular river valley. My dissertation looks into why this might be.

I am doing Bayesian statistics this weekend.
It's been said that there was a 150-200 yr gap where FM people stopped using a site type and then returned with pottery. Have ~200 C14 dates from 13 sites to see if that holds up. #ChangingtheNarrative

Really exciting news from the Ozarks! A bag of seeds dating to the Pre-Contact Period in North America was found and donated to the University of Arkansas museum. Absolutely amazing find and you can read more about it here:

Chase Earles is a Caddo potter. He makes traditional Caddo pottery, but he also makes some amazing pieces that mix traditional Native American themes with modern pop culture. Here are a few pieces he did. You can follow his page at: facebook.com/caddopottery

Will have a YT short out this week (~3min video). Its just some of the archaeological process. The hope is to demonstrate some of the process & allow people to ask questions along the way. In the future, I am making a full series on an excavation of my family's site (historic).

Went to visit local landowners and survey areas for sites on their property. Located petroglyphs and black earth. Can't share photos of sites or artifacts but here selfie from me hanging sideways from a tree to get a photo of some erosion occurring.

We'd informed a few people, such as the State Archaeologist, about the specific point type (Evans) of which we were initiating a morphological study but kept it quite so nobody could rush in & do a quick study ahead of us.
That was why formally making an announcement at the meeting was important.

1/ As promised, key topics from the paper I gave this past weekend. I examined settlement patterns in the Pine Hills of Mississippi. Cluster analysis identified 5 distinct groups from the Late Archaic to Late Woodland Period. In this, I did initial density, ecological, and social
