Trimble R8 GNSS


More notes...

The Trimble R8 GNSS requires more investigation. Given the possibility of mounds within the plow field, hardly visible when doing a walking survey, it has been suggested that I investigate using Real Time Kinematic (RTK) with accuracies in the mm. Spec sheet is here.

CAST does not have this new roaming unit but does have an earlier RTK unit. A couple places do rent the Trimble R8 GNSS:

Martin Instrument Survey Solutions in Austin.

This requires more research.

Arbitrary Notes

Well, since I should gravitate toward some aggregated method of jotting down notes regarding thesis thoughts, I figure what better place than this newly adopted blog. It also serves to be accessible anywhere and notes can also be added from anywhere - granted the all important internet connection.

So, here is a cut and paste from an email I keep sending and resending myself of random thoughts and notes regarding thesis methods. I can now delete that email.

- Include aerial imaging.. thematic mapper and LIDAR from CAST

- Chapter on geomorphology of the red river with evidence of meander of the river over time.

- Handbook of Geophysics in Archaeology

- GCD, Tom Jones, Terran Map, Crenshaw, Hatchell. A comparative study looking at intrasite settlement patterns of the Battle Mound site to support or not support the Terran Map observations. Where they out of it? Is GCD and other sites frontier sites with anomolous settlement patterns? Can specific settlement patterns be determined or are they so highly variable (single mound, hamlets, etc. as depicted in the Terran Map) that a pattern cannot be determined. What does this tell us about the Caddo culture and how they might have viewed their instrasite landscape?

Visit to Battle Mound & Crenshaw


Over the weekend I headed down to Magnolia, Arkansas to take a look at a couple mound sites that I am strongly considering for my thesis - Battle Mound and Crenshaw Mound. I plan on doing a geophysical survey at one (or both) of the sites. Battle Mound is a single mound site (although multiple mounds are to have existed) and Crenshaw has multiple mounds. I was able to meet the land owners at Battle and they are receptive to me doing research on the site. A recent email from Dr. Jamie Brandon brought news that land owners at Crenshaw are also receptive to me doing research there. My plan at this point is to gather as much historical information about both sites and in the coming months, make another visit to do some preliminary geophysical grids to get a better understanding of instrument capabilities and any issues I might encounter. I am concerned about the numerous historical occupations at Battle and the inevitable metal trash that would accompany them. However, I am anxious to get started and have many ideas about how to approach this research project floating about in my head as a result of my productive visit.
