We started this morning by taking a look at the uber-map of the site before opening a new unit. The reason we were opening one more unit, Danny explained, was because they had removed a concrete curb through that area a few years ago and thought there might be a large feature underneath.
Here is Danny showing us the location of the new unit on the uber-map. Yesterday Dave and I (well, mostly Dave) mapped the Smith's Fort units in 3-D. Today we looked at a 2-D representation of the features in our excavation area at Jamestown. Sorry the close-up is not very good, but you get the idea. I am not sure how often they dig features at Jamestown, but with a map like this they can immediately pinpoint features that were discovered and marked but left unexcavated. Then, in the future when there is all sorts of time and money for a full-fledged excavation, then can come right back and know just where to open their unit.
I am not sure if I mentioned it before, but the units are not placed arbitrarily. When Dr. Kelso first began the excavation in 1994, he chose a point as a reference against which all other points could be surveyed and plotted out. In surveying this point is called a datum, and it is often something that is not only stationary but that is also pretty likely to last a long time (like the corner of a building or - in the JR group's case - a monument.) Choosing a manmade structure is a great improvement over the way they used to do it in the 17th and 18th centuries, where property lines often included "such and such maple tree", making it difficult for researchers to know exactly where properties began and ended! Anyway, using the datum the JR group then plot where each 10' by 10' unit should go.
The backhoe saved us a ton of backbreaking labor and a ton of time as well. However, it was still a tough morning because we all took shifts parking our wheelbarrow near the backhoe, getting a few shovelfuls of dirt, and trucking it over to the dump pile. It was really hard work - more than in some of the other units because the roadbed was very gravelly and compacted. It made for dense, heavy wheelbarrows full of dirt. Thank goodness it was not 105 degrees like it has been sometimes - it was a cool 86 degrees as it's hottest today.
A couple of artifacts did come out of the overburden as we got close to the "B" layer. The most interesting was the blue and white piece of Delft in the picture.
Teal, working a couple units over, found this really amazing fragment of pipe bowl and stem. It includes the heel of the pipe (which would be sort of below the bowl) - can you see the maker's mark? It is very difficult in this small picture, but there is a definite "R" and another letter (maybe a "c" or a "G"?)
As Dan shoveled in our unit, he found this awesome worked point. It seemed pretty huge, and we wondered if maybe the Virginia Indians had started to work the point but abadoned it soon after (perhaps because it broke down the middle as it looks today?) We had to clean up just after this was discovered, but now I'm hoping that we find the back half of this point in our unit tomorrow, and that they mend together cleanly!! :D
