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.

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Unpublished report, 1965.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

Unpublished report, 1965.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
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

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.
