significance with respect to broader issues of resource intensification and environmental change.<br />

Feasibility of Using Protein Residue Analysis to Determine Materials Processed within Bed<br />

Rock Milling Features<br />

• Symposium 4 (De Anza North); Thursday, 2:45 PM<br />

This pilot project tests the feasibility of using Crossover Immunological Electophoresis (CIEP)<br />

analysis to identify plant and animal protein residues on bedrock processing features in order to<br />

test long-held assumptions. Positive antisera-antibody reactions (positive results) were obtained<br />

in about 17% of the processing surfaces sampled. Both plant and animal protein residues were<br />

identified. Thus, it appears feasible to use this analytical technique on bedrock surfaces.<br />

Collecting samples in the field presented unanticipated logistical problems that, when addressed<br />

in the future, will likely lead to a higher percentage of empirical data. We further explore the<br />

use of an alternative collecting technique as well as other analytical methods to improve success<br />

rates.<br />

Rock Features in the Mojave Desert: A Fresh Look at Locations and Functions<br />

• Symposium 3 (De Anza South); Thursday, 4:15 PM<br />

Rock features have been recorded at numerous locations in the Mojave Desert since the1920s<br />

and multiple speculations have been presented regarding their function. Recently eight sites<br />

exhibiting multiple rock features have been recorded within the Cady Mountain region east of<br />

Barstow. This desert phenomenon is under-studied and only loosely interpreted. This paper will<br />

present possible functions and time frames while offering insights into possible human behavior<br />

represented on a landscape level and the apparent density of these features in the Cady Mountain<br />

region. Recognizing this phenomenon in the field and the methodologies <strong>for</strong> recording these<br />

features will also be discussed.<br />
