资源简介：
Samples were collected along the Middle Fork of the John Day River in east-central
Oregon for a study of fluvial geomorphology. A total of 32 detrital charcoal/wood samples were
submitted for identification, and 11 bulk soil samples were examined for pollen and macrofloral
remains. These samples were recovered from soil pit or natural bank exposures along the river.
After successful completion of this phase of the study, an additional eight pollen, eleven
macrofloral, and two botanic samples were submitted to obtain additional information about the
local, prehistoric vegetation. Macrofloral, including charcoal, and pollen records will be used to
provide information concerning plant taxa that may have been present in this area
prehistorically.
