Description
Study of 23 pollen samples associated with archaeological sites in the Walhalla Glades district of Grand Canyon National Park yields surface sample data not consistant with prior research, possibly because the samples are actually of sediment deposited during the period the sites were occupied. Pollen record suggests local prehistoric cultivation in a paleoenvironment quite distinct from that presently occurring in this district.

DescriptionClassroom excercise study of 32 samples from proxy surface, dune and pithouse contexts. Analysis used pollen categories rather than traditional pollen taxa. Results suggest the site's occupation history incorporates 5 distinct episodes of ecosystem change.

DescriptionReport on this research has been lost, though pollen observed forms are filed with the site archaeological records.

Description
Squash and possible maize pollen in sediment samples from checkdams suggests the features are prehistoric and were used for crop production. No evidence that local environment was different when the features were used.

DescriptionPilot study of 13 surface and 9 archaeological-context pollen samples from 2 sites in the Black River Ranger District. Analysis suggests a local pollen chronology can be developed from such samples, but paleoecological interpretation would be difficult.

Description
Unpublished report, 1965.
Study of pollen samples from these two Reeve Phase sites was undertaken excluding Cheno-am and Compositae pollen from the pollen sum. Cross-dating suggests a five-horizon pollen sequence; three horizons are evidenced a both sites, the other two are from samples superimosed on the occupation floors of rooms. Dates between A.D. 1375 and 1490 are suggested for the sequence. Also discusses economically significant pollen types and presents cultural ecological interpretations. Published 1973

Description
Attempt to cross-date alluvial beds through pollen study of CCa horizon samples failed. Pollen concentrations too low, though pollen preservation was adequate.
