AAS Dig Rescheduled/New Rendevous Point Named

Monday, March 30th, 2009

The AAS Volunteer day has been rescheduled for this Saturday 4 April 2009. The 8:00AM meeting time is the same, but the place where we will assemble before moving to the dig site has been changed. Below is an up dated park map showing the new rendevous point. For a map to the park please see the 10 March 2009 blog post.  If you plan to be here contact Steve Meredith or email me at jackbergstresser@aol.com so that we will know how much gear to have ready. For more information see the new Alabama Archaeological Society web page: http://www.aas.mspanos.com/index.shtml Mary Spanos has done a fantastic job!

Updated Map/ New Rendevous Point

After you cross the bridge at the Grist Mill, drive another three hundred meters then turn right and go another 250 meters across a bridge over a dry wash and up a rise to the overflow parking area to the rendevous point.

One reason we rescheduled the dig

Every morning that it rained last week, the ford at the Grist Mill, here visible only as a line of white water, became impassable.

A good reason to test the Mill Pond Site

The Mill Pond Site
The Mill Pond Site is located on beautiful little a bend in Mill Creek. Last week, with the creek as high as I have ever seen it in my three years at the park, the site was still a comfortable eight to ten feet above the water level.

Civil War Iron Forge Confirmed.

Monday, March 23rd, 2009
Beth McCown's discovery last week turns out to be a gungion that was once attached to a water wheel shaft. One of four tabs that secured the gungion to the wodden shaft is still attached. The scar along the top edge remains from one of the tabs that was broken off.

Anna McCown's discovery last week turns out to be a gudgeon that was once attached to a water wheel shaft. One of four wings that secured the gudgeon to the wooden shaft is still attached. The scar along the top edge remains from one of the wings that was broken off.

The one day long archaeological investigation of the suspected Civil War Williams and Owens iron forge removed all doubt that this was the site of the short-lived ironworking operation. In addition to the gudgeon, we confirmed that a stone cluster along the banks of Roupes creek was once an intact stone wall, probably a water wheel pit.  Back away from the creek, about 200 yards, two large stone piles proved to be fire place bases. We are grateful to the Gilmore family for permission to investigate this important site which is located on their private property.

Stone wall is probably a remnant of water wheel pit.

The wall is probably a remnant of the pit that housed the water wheel that drove the shaft that powered the iron forge hammer.

Shovel Testing the Stone Piles
The crew dug five shovel tests at the site of the two stone piles discovered earlier in the week. Machine cut iron nails, whiteware fragments and several pieces of glass suggest that these piles were the foundations of chimneys for at least one house. Scattered brick fragments in the vicinity suggest that they were constructed of brick.  Near by, the crew spotted the suspected remains of a spring house. Further away, an addition stone pile may be remnants of another domestic structure.

CivilWar Forge Rediscovered

Thursday, March 19th, 2009

For years we’ve known of the existence of the Williams and Owen Forge down Roupes Creek from the blast furnaces at Tannehill, but recent discoveries suggest that the site was more substantial than just a simple catalan forge operation.  The remains of a crib dam on the creek and possible stone foundations are visible near the water’s edge but a new survey has revealed two stone foundations, a stone lined well and brick scattered over an area well back from the creek.

Floods over the years have gradually dislodged the logs used in the crib dam that impounded water to drive the cam shaft that activated the forge’s large helve hammer.  This large log was washed up on the north bank of the creek about fifty feet downstream of the dam.
The log was notched and thick wooden pins were attached at regular intervals along the log.

Located about 100 feet down stream of the crib dam, these stones may have been part of the wheel house where a water wheel that turned the cam shaft that drove the forge hammer was located.
An solid iron bar eight inches in eighteen inches long was the first discovery of a very informative survey.

An solid iron bar eight inches in diameter and eighteen inches long was the first discovery of a very informative walkover of the site.

Anna McCown, anthropology major from the University of Alabama at Birmingham discovered this large iron bar as we began to move inland from the creek in search of surface visible remains of the Civil War era iron working operation.  The walk over was part of advance preparation for a survey of the site this weekend by current students and recent graduates from UAB and the University of Montevallo. The survey is part of the larger study aimed at recreating the historical landscape at Tannehill and Brierfield and the intervening sixteen mile expanse of the Cahaba River watershed that separates the two State Parks managed by the Alabama Historic Ironworks Commission.

Anna provides scale showing this stone pile to be almost three feet high and around eight feet square. Made of cut stone, the remains were so covered with humus and leaves that their exact shape and dimensions were not readily visible.
Stone lined well.

The well and the two stone piles are located in a large flat area that was spacious enough to have accommodated multiple structures.  Scattered pieces of brick in the vicinity suggest that some of these potential structures were buildings or dwellings. We are hoping that our preliminary archaeological testing this weekend will begin to tell us more about the nature and extent of this important site. One thing is already clear, the site is much larger than we originally suspected.
We did a quick video scan of the terrain where the two stone piles and well were located. Check it out by clicking on the link below.

Alabama Archaeological Society Volunteers to Test Prehistoric Tannehill Site

Tuesday, March 10th, 2009

Members of the Alabama Archaeological Society will assemble for a voulnteer dig at the Tannehill Ironworks Historical State Park on Saturday 28 March 2009.  We will be testing a Woodland period site located on a terrace above a bend in Mill Creek. Below are maps to the park and to the assembly area where we will meet at 8:00AM.

Map to the Park.

When you enter the park, turn left and drive to the eastern end of the park. We will assemble at the Overflow Parking Area shown on map above at 8:00AM.  Check out this blog after the dig on 4 April for a report of our findings.  If you are late and have to walk to the site on your own, the Grist Mill Trail begins right next to the Grist Mill. You will have to walk to the trailhead from the overflow parking area.
