1.! Stratigraphic environments. 2.! Dating – then & now. 3.! Stratigraphic controls. 4.! Records management during excavation. 5.! Summary of the assemblages. 6.! Where in the succession does the Tucannon Phase end? 7.! Effects of rodent disturbance in floodplain loess (Stratum III). 8.! Raw material: sources, technology, trade, & regional interaction. 9.! Fresh water mussel shell over time – implications. 10.!Fishing technology – implications. 11.!Faunal remains – potential for future analysis. 12.!Faunal remains – rodents in two contexts. 13.!Cobble implements – reduction and edge-ware studies. 14.!The value of manuports and fire-cracked rock. 15.! An unusual artifact from Assemblage 3C (Tucannon Phase).

Flaked bone tools are common in the Cold Springs and Tucannon Phases at 45Co1. Flaking is used to shape bone before grinding and to create simple flaked tools such as side scrapers. Other examples are likely to be ground tools broken in the early stages of manufacture.
