understanding of lake bathymetry (underwater topography) and the collection of 14lake sediment samples. Fifteen soil samples for micromorphological analysis werecollected from the exposed scarps of fi ve previously excavated or destroyed tumuliover the course of two days. Over a total of four days, we prepared architecturaldrawings of the previously undocumented chamber-tomb complex of a tumulus,and visited 20 other tumuli with the aim of reassessing the conditions of previouslydocumented tumuli in central Lydia. Finally, lab work included preliminary analysesof fi nds collected in 2006 and re-analyses fi nds from the 2005 season. In additionto database cataloguing, photography, and drawing, small samples were takenfrom 289 sherds for chemical analyses in the United States. These preliminaryresults from the 2006 season continue to indicate the potential for future years ofsurvey and, eventually, new excavations around the Gygaean Lake.II. ARCHAEOLOGICAL SURVEYThe regional focus of our work in 2006 was the area west and northwest ofthe Gygaean Lake comprising small valleys, shrub-covered ridges and hilltops,and lower foothills leading down to fl ood plain and the lake itself. As in Bin Tepe,revisited again in 2006 but the primary focus of the 2005 season (Roosevelt 2007),the open landscape provides for good visibility and many sites can be locatedeasily by sight during fi eld walking (Map: 2; Fig. 1). The western and northwesternlakeshore areas are almost entirely covered by thick layers of alluvium andrelatively recent lake muds and, thus, we limited survey in these low lying areas in2006, concentrating instead on the uplands.We recorded the locations of all survey units and surveyed features using handheldGlobal Position System (GPS) receivers, marked their locations on 1:25,000scale fi eld maps, and documented their locations and conditions on standardizedforms and with digital photography. For tumuli, we recorded location, diameter,height, and condition, and noted anything of special interest, including locationsand dimensions of looters’ tunnels, visibility, and accessibility and composition ofchamber-tomb complexes, among other details. Survey units comprised agriculturalfi elds and other geomorphological units, and their modern condition and use wererecorded in addition to the presence or absence of cultural materials. Along thec. 2 meter-wide survey track walked through each survey unit, we counted allcultural materials encountered (e.g., ceramic sherds, tiles, lithics), and collecteddiagnostic materials for purposes of assessing the date and type of cultural activity306
