"Featherstone" from the Wash Tray

Most of our artifacts are discovered in the field, but on rare occasions they turn up in the lab. This was the case with an engraved siltstone pepble found this past summer at the Heckleman site. What appeared to be just a rock in the field, turned out to be a finely-engraved siltstone pebble, but it was only recognized once it had been washed. It measures about 5.5 cm in length and came from Feature 10-30, a large cooking pit that contained abundant charcoal in a matrix of greasy black soil. Not much else was found in the pit other than FCR, but luckily we kept this inconspicuous stone. Once washed, it revealed an intricate engraving of what look like turkey or hawk features, arrayed in a fan-like pattern.
Engraved stones are rather uncommon, and we do not understand why they were made or how were they used. Over the years, fragments of slate celts or pendants have been unearthed on Late Prehistoric period village sites in northern Ohio. Some of these bear depictions of birds or human faces and cross-hatched lines which somewhat resemble Mississippian iconography more common in the southeastern United States. But to my knowledge, the depiction of bird feathers on the Heckleman "featherstone" is unique. I liked this design so much, I had it put on our annual field school T-shirt. So, the lesson is, keep your eyes open in the field AND in the lab.

Fine Pottery from an Ordinary Pit

Over the course of our five week field season, we have found pottery of varying quality. In general, the Early Woodland ceramics from the region are the most coarsely made, as exemplified by the Leimbach series pottery recovered from the oval enclosure ditch and several pits. The net-impressed sherd discussed in an earlier post is a notable exception to this general trend. Another surprising discovery is the collection of pot sherds recovered from Feature 10-16, a large, but not very distinctive pit feature found during week four. Unlike most other features, the pottery in Feature 10-16 was concentrated into two clusters. These can be seen near the bottom of the pit in the cross-section image shown below. These sherds were very fragile when uncovered and could not be examined closely in the field. Once I had time to inspect


the sherds, I discovered several fragments of the rim and body sections of a medium-sized vessel. The rim sherds exhibited a surface treatment of very fine cord-impressions oriented vertically to the lip of the pot. These impressions were most likely made by the application of a wooden implement wrapped in some of the finest cordage I have ever seen impressed on a Woodland vessel. This cord-wrapped paddle would have been applied when the pot was still wet, prior to firing. The closeup of a rim and neck segment shown below reveals the great expertise of the Native American potter who made this fine vessel. If you look closely, you will note that the parallel cord impressions change orientation on the lower neck (just left of the nickel) from



vertical to horizontal. This is a rather common convention on Middle and early Late Woodland pottery of the region. Also found in this pit was a Flint Ridge bladelet fragment which suggests that this vessel was made during the Middle Woodland period, although we cannot be sure unless we run a radiocarbon date on charcoal from the pit. We have additional fragments of this pot now being cleaned in the lab. Hopefully we will be able to reconstruct enough of this vessel to reveal the overall shape and size of the pot and thereby determine is function and period of origin.

Following the Stockade

During our last two weeks of the 2010 field season at the Heckleman site, we had several tasks to complete. One of the most important of these was one last ditch effort (no pun intended) to trace the stockade lines eastward. You will remember from earlier posts that in Week 1 we uncovered two distinct lines of large post molds, which I interpret as stockade posts. In the map below, both lines are clearly visible running obliquely across the western end of our excavation.

The inner or east line was traced for about 12 meters to the northeast, at which point it crossed the fill of the oval enclosure ditch (Feature 09-18, shaded in gray above). A much shorter section of the outer or west line was exposed. In the image below both lines are marked by orange survey flags and indicated by arrows; green arrows show the western line, white the east line, and the location of Feature 10-02 is indicated by the red arrow (my most colorful image yet!).


We cross-sectioned short sections of posts in each stockade line, and they proved to be rather large and deeply set. The posts of the east line (shown below) are slightly larger than the west line and range from 7 to 10 cm in diameter and extend from 23 cm to 40 cm below datum.


To trace the east line even farther, I decided to excavate a one by ten meter test trench running northward from the 520N, 520E stake. We had some assistance in this task from students and CMNH Education Division staff as part of a two-day class in Archaeology. These young folks and their instructors: Mark, Nancy, and Char, shovel-shaved some of the hardest, driest, and dustiest plow zone soil we have encountered all year from this trench and made our job much easier (see image below). In the process they found a good quantity of chert flakes and other debitage, FCR, and even one triangular point, which probably dates to around AD 1400.


The point of this trench-digging was to intersect one or both of the stockade lines as they made their way to the northeast. Despite our best efforts, we could not confirm the presence of either stockade line within the trench, although we did exposed several scattered posts and two pit features. One of these small pit features contained a bladelet fragment and a plain-surfaced pot sherd, both are indicative of the Middle Woodland occupation of the Heckleman site. The other pit contained nothing. I should note that it is difficult to identify even a distinct line of post molds in a one-meter wide trench, but I gave it a shot. But this will give us something to shoot for again next season.
