[We Dig Hampsted Hill] Lost a belt buckle at Camp Patterson?

Ryun PapsonWith just a few days of digging left for We Dig Hampstead Hill, we’re still finding some incredible artifacts from the early history of Patterson Park. This morning archeologist Ryun Papson found a Union soldier’s belt buckle (almost confusing it with a common oyster shell at first glance). If you look closely, you’ll see the letters “U” and “S” in the oval-shaped buckle above.

[We Dig Hampstead Hill] Dr. John Bedell explains the stratigraphy of the 1814 fortifications

Thanks to Dr. John Bedell for sharing his experience digging this past Saturday and explaining the stratigraphy that shows the remains of the 1814 earthworks below Observatory Hill at Patterson Park.

Dr. John Bedell

In Stratigraphy, Patterson Park our third attempt to dig a trench across the 1814 fortification ditch we finally got the profile we were looking for. In our first two trenches we could see what might have been the 1814 ditch, if we squinted right and waved our hands for effect. Honestly, if we hadn’t known what we were looking for we would not have described the soils in either place as a back-filled ditch. But this third profile is exactly what we were hoping to see.

It’s hard to make out but if you enlarge the pictures above and look closely you can see five distinct layers in the soil:

  • At the top (A), is dark grayish brown topsoil. Below that is a mixed-up layer with numerous rocks (B), which is landscaping fill put down in the early 1900s when the Olmsted Brothers beautified the park. We have found both of these layers everywhere we have dug.
  • Beneath the landscaping fill is the 1814 ditch. The top layer of in the ditch (C) is a mix of the landscaping fill with the older trench fill. Beneath that is a layer of sand (D) that washed into the ditch in the decades after it was abandoned, untouched since before the Civil War.
  • Below that (E) is the natural subsoil.

Greg Katz using an auger Since we feel like we have a good grasp on the soils we are looking for, we have started trying to trace the trench across the landscape using smaller holes. Using a bucket auger you can extract a narrow column of soil, which you can lay out next to a measuring tape to get an approximate idea of the stratigraphy below the surface.

We tried our first group of auger tests 75 feet from our last trench, and we think we identified the fortification ditch there, along the same line. But 150 feet down the line we did not find it, so we suspect that it has curved. Fortunately, we still have a few more days to sort this out.

[We Dig Hampstead Hill] School groups, mysterious drain pipes and a musket ball

As rain today and tomorrow keeps our We Dig Hampstead Hill project team inside (catching up on all of the less glamorous paperwork!), we’re excited to share a few results from our second successful week in the field, what archeologist Greg Katz says is, “Good stuff, and more good stuff to come!”

Last week, we welcomed five school groups for a hands-on field trip at Hampstead Hill including students from Thomas Johnson Middle School, Morrell Park Middle School, Patterson Park Public Charter School, and Hampstead Hill Academy. Special thanks to our school outreach coordinator Theresa Donnelly for supporting these visits and to Jefferson Patterson Park and Museum (whose “Mystery Objects” learning activity has been a huge hit with these young archeologists-in-training).


We also made great progress in locating the remains of the defensive earthworks and finding some exciting artifacts that connect us to the people who camped along that line during the fall of 1814. Fieldwork Director Greg Katz has shared his perspective on the second week of the project:

2014-04-25 15.20.37We had strong volunteer support, and we were able to take our test units (started last week) down to 3-4 feet below surface into some very interesting nineteenth-century deposits. We found the eastern and western edges of the tavern structure, as well as the base of the earthen cellar. We recovered lots of interesting artifacts from the tavern excavations, including a large assortment of buttons and ceramic wares, and smaller amounts of bottle fragments and other domestic items. One of my favorite finds from this area is a Goodyear rubber button, probably produced in the 1850s, when the former tavern was home to the Keeper of Patterson Park. Nothing military in nature was found in the tavern structure, which was unexpected.

Some military items did turn up in the test units north of the Observatory, including a gunflint and a musket ball. By the close of the week we were fairly confident that we were near the base of the 1814 fortification ditch in the excavations both north and south of the Observatory.

2014-04-23 12.31.14The testing south of the Observatory found some very interesting layers of soil and elements of an older drain system possibly dating to the nineteenth century. A relatively shallow ditch, suggestive of the 1814 fortification ditch, was found approximately 1.5 feet below the ground surface. At the base of the ditch was a small brick storm drain. Approximately two feet lower we encountered another ditch that we think is the actual trench from the 1814 earthworks. Our current theory is that the upper ditch is a historical reenactment of sorts – that at some point in the nineteenth or early twentieth centuries a ditch was dug to recreate the historic rampart. The drain system may have been installed to keep the recreated ditch from filling with water. This may be an example of how each generation of Baltimoreans comes to learn the city’s history, and rediscovers and reinterprets the past. Good stuff, and more good stuff to come!

[We Dig Hampstead Hill] Dr. John Bedell spends the day at Día del Niño

Thanks to John Bedell for sharing his reflections on digging in Patterson Park during Día del Niño and a few photographs from a sunny day of archeology, music, and art.


I spent most of today in Patterson Park again, helping my crew and our volunteers keep looking for the 1814 earthworks. This is proving to be more of a challenge than we thought a week ago. I spent my day in the south trench, which you can see above in the early morning light. We thought we had found the fortification ditch here last week, but that turned out to be a brick-lined drain dating to around 1900. (Hence the bricks piled around the trench.)

We had to dig two feet deeper to reach what we hope is the top of the actual 1814 ditch. But we are now 4 feet down and can’t take the trench any deeper for safety reasons, so we will try to verify that the ditch is what we think by digging a couple of shovel tests in the trench floor. I did a fair amount of digging myself today, for the first time in months!
