Prehistory of the Southwest-
Archaeology of Nancy Patterson Village



(Reposted from 05 August, 2014 blog post)

Nancy Patterson Village
The archaeology of Nancy Patterson Village is easy to classify as the highlight of just about any trip. During the summer of 2014 we spent 10 days focused on excavation at the site, examination of the artifacts, and formulating a draft report. We give a brief account here of that time.

Nancy Patterson Village is a Pueblo III (AD 1100- 1250) with underlying P II (AD 900-1100) habitation. It is located in Montezuma Canyon and at its height had some 300 rooms with as many as 30 associated kivas. There are two distinct parts to the site- the upper, mesa-top ruins and the lower, flood plain ruins.  Culturally it is related to nearby Mesa Verde.

The goal of the current excavation at Nancy Patterson Village is the definition of architecture on the outside edge of the lower, flood plain settlement area. This area is considered to be the latest construction at the site, and therefore is assumed to have the shortest occupation sequence. Excavation defines not only the physical, spatial boundaries, exposing the actual walls and floors, but tells us the temporal boundaries as well- how long the structure was in use. Charcoal samples taken from three separate levels, the earliest found in the fill below the first floor, will give us an idea of the construction date and the date of final use, now assumed to be about 1275 ACE. The occupation sequence of our unit is confirmed to be later based on the pottery we found as we excavated. All of the pottery was later, Mesa Verde style pottery.

Mesa Verde corrugated wares from our Level 2, found directly on our final floor. There appear to be 3 distinct jars, with some shards showing intense burning that likely did not occur during normal use.

We found a number of interesting features in our unit, including what appeared to be "post-abandonment" (happening at some point after the room fell into disuse) burning and pottery left on the final floor. We found numerous lenses of charcoal, some of which may have been hearths within the room. We also found the masonry outline of a metate, a grinding stone that had been imbedded in mortar in a corner of the floor. The outline of the metate was clear, and the small, flat pieces of sandstone embedded in mortar that were used to level and secure the metate were still in place. Finally, if the fill under the floors is an indication of the intensity of occupation, that is, if there is more trash in the floor fill we can assume the was more trash to use as fill, this tells us that there was likely more going on to create that trash. The fill under the floor about mid-way down was replete with artifacts- pottery, flakes, cores, hammer stones, part of an axe, and a mano were all found in a very small area.

Salmon Ruins
Besides the excavation, we made a side trip down to Salmon Ruins near Bloomfield, New Mexico. It had been years since I visited there; Nicolai had never been. Seeing the excavated and consolidated ruins made for a good contrast with Nancy Patterson Village. Salmon is a large pueblo located near the San Juan River. It has two distinct occupation sequences- its initial construction by Chacoan peoples around 1090 ACE, followed by a period of decline and depopulation by about 1125 ACE (referred to as abandonment in the literature at the site- but I am not a fan of that word.) The second distinct occupation begins about the same time and ends around 1280 ACE. The second group of inhabitants come from the San Juan area and some of the literature indicates there are distinct ties to Mesa Verde.  One argument for this relationship is the distinct change in architecture, including the shape, size, and location of kivas, resembling those of the Mesa Verde region more than the Chaco region.
