Red River Update: August 6
Paddlewheel
Monday, August 6, 2001
The river continued low on Monday, with less
current than previously. The water level had risen by a few inches, with
only the end of the starboard paddlewheel shaft exposed above the surface.
Monday was a full schedule day again, with
teams working to complete and refine drawings made previously. Daniel Seib,
a graduate student at Indiana University Bloomington (http:www.iub.edu),
worked with field school student Cecile Brothers of Long Beach City College
(http://www.lbcc.cc.ca.us/) to refine their drawings of the starboard hull
framing just aft of the flywheel trunk. Recent natural scouring, along with
dredging by the project team, has exposed the starboard side of the hull
from the keel, along the centerline, to the upper edge of the hull where the
wale has broken off. This section of hull offers a valuable look at how the
boat was constructed. Additionally, as the stern of the boat is broken to
port and twisted, the section of the hull immediately adjacent to the
flywheel is relatively intact and easy to understand.
On the port side of the boat (toward the
Texas bank of the river), scouring has partially exposed the boat’s
paddlewheel timbers and one of the flanges, the iron discs that held the
wooden paddlewheel arms in place. In their first dive of the day, Lucius
Martin of Long Beach City College and Howard McKinness of the Oklahoma
Historical Society began dredging to clear away additional sand. Their
objective was both to document the paddlewheel and to determine if there was
a third ring of paddlewheel arms on that wheel, outboard of the two that
have been observed. "There were a lot of buried snags on that hub that we
had to cut loose," Martin said, "to get the dredge head in to work. We got
most of that cut away, and then Brandon [Talley] and Marlo [Thomas] were
able to come in after us and finish that job." Talley (Southeastern Oklahoma
State University, http://www.sosu.edu/) and Thomas (Long Beach City College)
confirmed the presence of a third ring outboard of the first two, and
indications of what may the paddlewheel support structure outboard of the
wheel itself.
Another team worked to refine existing
drawings of the heavy-timber trunk surrounding the boat’s central flywheel.
The starboard side of the trunk could be traced forward for almost 25 feet
ahead of the flywheel shaft before disappearing into the sandy bottom. This
team also re-trilaterated the precise positions of several key points on the
boat’s central machinery section. Getting these positions determined
precisely is crucial, as almost all the other datum points on the vessel are
derived from those on the machinery.
One crew member lost a gold and platinum
wedding ring today when it got caught on a snag, but found it again about 45
minutes later—a remarkable feat, given the six-inch visibility and shifting
riverbed.
