<p>The students in my lab class are pushing hard to finish their projects. They&#8217;re all working on materials from Aniakchak &#8211; mostly the 2007 collections. They&#8217;re producing the first real data from these materials. I have students analyzing shellfish, mammal bones, chipped stone waste flakes, chipped stone tools, and bone tools. Other students are working on the catalog data and illustrations. It&#8217;s my favorite part of the class. I have 16 research assistants &#8211; all generating data and addressing questions. It&#8217;s a blast.</p>
<p><span id="more-223"></span></p>
<p>They&#8217;ll be posting the results of their studies on the Aniakchak <a title="Aniakchak Wiki" href="http://aniakchak.wikispaces.com/" target="_blank">Wiki</a>. Check it out and see what they have to say. I&#8217;ve been telling this class that they have to do better than the 2006 class &#8211; analyzing larger samples, <a href="http://bhoffman.edublogs.org/files/2008/12/2007-lab-class-cs-tool-group_25.jpg"><img class="alignright size-medium wp-image-226" style="float: right" src="http://bhoffman.edublogs.org/files/2008/12/2007-lab-class-cs-tool-group_25-300x192.jpg" alt="CS Tool Group - Matthew, Josh, Emily" width="300" height="192" /></a>creating more stunning graphics, and writing better reports. The Aniakchak Wiki will have both the 2006 and 2008 reports, so everyone will be able to see if this year&#8217;s class really does &#8216;kick butt&#8217; on the 2006 class as they claim.</p>
<h6 style="text-align: right"><em>CS Tool Group &#8211; Matthew, Josh, and Emily </em></h6>
<p>What I&#8217;m most curious to learn from this year&#8217;s analyses are some of the differences between occupations at Aniakchak. This year&#8217;s class is focusing on a single 1 x 1 meter excavation (N462E455) that produced almost 2 meters of cultural deposits. The upper component started with a Koniag house floor (Strat II). Immediately below this floor was a thick midden deposit (Strat III) that probably dates to about 1200 years ago. About 80 cm below this midden is a very rich deposit (Strat VIII) that included a lot of shell midden, micro debitage, and burned bone. It looks this deposit could include a house floor or similar context. This deep deposit produced some fiber tempered ceramic sherds, suggesting a Norton tradition occupation dating around 1700 years old. Another 20 to 50 cms below the Norton component is another relatively rich deposit. This basal component had spongy wood preserved and a scattered midden. We haven&#8217;t dated this component, but it may predate the Norton component by a couple of hundred years.</p>
<p>I&#8217;m excited to see what the students have to say about these different components. It&#8217;s sometimes hard to tell anything when we&#8217;re digging. There is just so much blue mussel shell and fish bone that it&#8217;s hard to pick up any other patterns. This is why I always get pumped up when we get to this stage in the lab work. After hours and hours of sorting and cataloging, we&#8217;re finally going to find out what we have discovered.</p>

			<content:encoded><![CDATA[<p>I spent today messing around with photographing a basalt point from the King Salmon site. I struggled getting the lighting and the camera settings to capture all the details of the flake scars and yet still show the proper black basalt color.</p>
<p><a title="UGA052.2003.0756 3 views" href="http://bhoffman.edublogs.org/files/2007/06/copy-of-uga20030756-3-views-w-scale_35.jpg"><img src="http://bhoffman.edublogs.org/files/2007/06/copy-of-uga20030756-3-views-w-scale_35.thumbnail.jpg" border="1" alt="UGA052.2003.0756 3 views" hspace="10" vspace="10" align="left" /></a>Here is the end result. I&#8217;m using a digital Nikon D70s with an old 105 mm macro lens (the lens doesn&#8217;t work with any of the camera&#8217;s electronic functions). We have a pretty basic photo stand and lamp set up in our lab. I use a frosted glass plate to lift the artifacts above their shadow. For editing the images I have an old copy of Corel Photo-Paint left over from my dissertation days. I&#8217;d never stitched images together before &#8211; so I felt pretty pleased with myself that I could figure it all out.</p>
<p><span id="more-109"></span>I know I&#8217;m behind the times when it comes to artifact illustrations. I&#8217;m always really impressed by good illustrations. Some of the best work I&#8217;ve seen recently is being done by people using scanners. I like the idea of using scanners since you&#8217;d get images of a uniform size. One of my goals for the King Salmon photo documentation is to be able to combine into a single image what ever set of artifacts that I want. My results today will work, but I&#8217;m sure there are easier ways to get the images. Any ideas?</p>
<p>I&#8217;m actually very intrigued by the interplay between art and science, especially when it comes to illustrations in archaeology. I like crisp, simple photographs and drawings when I am documenting my work. But on this blog and in my talks I want illustrations that capture both the objects and sites, but also people. The photograph of the basalt point is effective at capturing the object&#8217;s details, but is otherwise a boring image. I much prefer photographing objects being held by a human hand and with a natural background when I want a more <a href="http://bhoffman.edublogs.org/category/artifacts/">interesting image</a>.  I feel the same way about field photographs. Stratigraphy profile shots are a part of virtually every archaeological report and conference presentation. Pictures of very dark brown soil grading into dark brown soil aren&#8217;t all that exciting to look at, even for other archaeologists. Having a crew member working off to the side, though, and the image has some zest. Like most archaeologists, I take some boring pictures for<a title="Aniakchak shell midden profile" href="http://bhoffman.edublogs.org/files/2007/06/p7290473-f25-profile_25.jpg"><img src="http://bhoffman.edublogs.org/files/2007/06/p7290473-f25-profile_25.thumbnail.jpg" border="1" alt="Aniakchak shell midden profile" hspace="10" vspace="10" align="right" /></a> documentary purposes only. But I like to add a little something for the astute observer. Take a close look at this profile of shell midden lenses at Aniakchak and you should be able to spot a Star Wars <em>Boba Fett</em> doll with his arms raised in triumphant celebration of a nicely cleaned wall.</p>
