Comments
Any additional information observed during analysis
not covered by analyzed attributes.
Flotation of all feature fill samples was completed by Cannon Heritage Consultants in Logan,
Utah. A total of 111.7 liters [149.3 kilograms (kg)] of feature fill was subjected to flotation (Table
5). The resulting heavy and light fractions were returned to Tetra Tech for processing and analysis
using standard techniques as outlined by Miller (1988). The heavy fraction was visually inspected
using a mounted and lighted magnifying glass. All light fraction was visually inspected using both
a digital and 10X binocular microscope. Any encountered potential artifacts were then analyzed
according the appropriate artifact class. The results of each artifact's analysis were recorded in
the appropriate spreadsheet. Macrofossil identifications were made using seed/plant reference
manuals (ex. Martin and Barkley 1961).
