Geologic Work at the Mitchell Locality

The Mitchell Locality is a large portion of the Clovis Site (LA3324) lying along the northwest margin of the prehistoric pond and extending into the slight upland rise to the west.  Over the last few years, we have been fortunate to extend our researches in this direction primarily through geologic coring.  The best available overview of the Mitchell Locality is Anthony Boldurian’s summary in Plains Anthropologist 1990.  The area is primarily known for the extensive Folsom-age materials found there but has a smattering of older and younger artifacts scattered throughout.

There was an intent to core more in this area but the soft sand created problems for both the machine and vehicle access.  Devising Plan B for the autumn.

Up on the Mitchell Locality, the sparse cover wheat allowed clear view of the surface with many small flakes visible.

We were fortunate that the great wealth of geoarchaeological knowledge of the southern high plains was present in the form of Haynes and Holliday.

The fine sand overburden varies throughout the site and can be over 4 meters deep.  In this area, it is only about 40 centimeters outside the arroyo.

I’ll keep posting as we learn more.
