The following time
lapse videos showing various aspects of the excavation this
season. They were made with a Kodak digital camera that was
programmed to record a photo every five minutes (how
we do it). Some videos
are shorter than others for various technical/logistical reasons.
We also have time lapse videos from
2001 and
2002. |
| |
One of this year's
highlights is watching a cast being made of a portion of the site
(see June 23 and the days that follow). |
| |
Warning: These
files are large. Most are over 3 mb. You will want a
fast connection (DSL, Cable, or T1) and you will need an AVI
viewer. |

June 14 |
Site
setup. Taking down the black plastic that protects the site
during the winter and putting up the tarp that keeps the rain out
while we excavate. |
|
June 16 |
In the
morning we give an introductory tour of the site to the
excavators. Then, as the day progresses, the total station
is installed on the right and excavation begins on the west
section. |
|
June 18 |
Excavation on the main two areas for 2003. To the left is a
portion of deposits resting over the burned layer (Bordes' XYZ,
our 8). To the right is what remains of our excavation of
the west section from the top to bedrock. |
|
June 19 |
This
one focuses on the burned layers (the dark levels at the bottom).
Not much happens in the morning while we discuss our plans to make
a cast of the section first. This cast will document the
hearths in these levels. In the afternoon, Dennis Sandgathe
can be seen cleaning the section. |
|
June 20 |
More
on the burned layers. Paul Goldberg can be seen making
observations of the freshly cleaned section. |
|
June 22 |
This
very short time lapse documents work on the west section. |
|
June 23 |
Back
to the burned layers. Not much happens in the morning, but
in the afternoon you can watch the process of putting the first
layer of latex on to the section. |
|
June 24 |
More
latex. By the end of the day the section is completely
covered. |
|
June 25 |
What
comes next is a coating of fiberglass. The latex molds to
the details of the section but is not rigid. The fiberglass
then supports the latex. In the afternoon you will see work
done on the corner to build a kind of fiberglass joint that will
help them put the cast back together in the museum. |
|
June 26 |
We
changed the time lapse to one minute, but even so it goes fast.
When the time lapse starts half of the cast is already off.
Next, we watch them remove the fiberglass from the right side
(this is very fast) and then slowly peel the latex from the
section. The latex pulls with it a little bit of sediment.
The latex mold is then lifted onto the fiberglass to be
transported back to their workshop where they will make a positive
from this negative impression of the section. In the afternoon the
camera switches to the west section where we are nearly down to
the bedrock. |
|
June 27 |
EDM
Cam. In this time lapse we mounted the camera on top of the
total station (EDM) we use for mapping artifact locations.
This video gives you the total station operator's view of the day.
Note that in nearly every shot there is someone holding a prism
(the bright circular light that looks like a flash-light aimed at
the camera). Since the images are in essence randomly timed,
this gives you an idea how busy the total station is during the
day. At the end of the day we see a visit by Princeton
University students. |
|
June 29 |
Now
that the cast is finished, excavation starts again on removing
the sediments over the burned layers. |
|
June 30 |
Back
to the west section. The right half is no down to bedrock. |
|
July 1 |
More
on the west section. |
|
July 2 |
The
west section continued. |
|
July 3 |
Back
to the deposits over the burned layers. |
|
July 4 |
More. |
|
July 5 |
In
this video you can see that we are almost on the burned layers.
You can also see that we are mostly working through large rocks
that represent a partial collapse of the rock-shelter during
Mousterian times. The board across the bottom is to protect
the burned layers. |
|
July 7 |
Extreme close-up. In this one the camera is looking down the
length of the excavation. It gives you a great close-up view
of the process. |
|
July 8 |
Here
we pull back and give you a feeling for the activity that goes on
at the site. To the left Dibble and McPherron are doing
stone tool analysis. To the right the burned layers are
being worked. |
|
July 9 |
This
one starts with the work on the burned layers and then turns a bit
later in the day to include the total station operators. One
person is doing the shooting and one person is working the
hand-held computer to save the recorded data. |
|
July 10 |
Here
we have the burned area and the west section at the same elevation
and are working them together. |
|
July 11 |
This
is the first video in a series where we document a portion of the
excavation of the burned layers from a close-up, bird's eye view. |
|
July 12 |
Continued. Keep an eye on the cookie. |
|
July 14 |
Continued. |
|
July 15 |
Continued. By the end of the day we have reached bedrock. |
|
July 17 |
Here
we feature jack-hammer work on the south section in an effort to
make the wall vertical. The work is difficult because of the
large blocks of roof fall that have to be trimmed. |
|
July 18 |
What
happened on this day is a secret. Just kidding. We had
to put a tarp up for safety reasons. Chips of stone from the
jack-hammer could hurt someone working in front. |
|
July 20 |
Here
we are finishing work on the west section. |
|
July 21 |
More
work on the west section and we are also excavating a bit more of
the burned layers. |
|
July 22 |
Continued. |
|
July 24 |
Continued. Part of what you see in this one is a film crew
working at the site as well. |
