We are greatly indebted to Julio Betancourt and Tom Van Devender, who supplied most of the packrat middens we have analyzed, and permitted us to cite unpublished radiocarbon dates. Preliminary drafts were edited by J. L. Betancourt, H. J. B. Birks, Ken L. Cole, Paul S. Martin, Robert S. Thompson, T. R. Van Devender, H. E. Wright, and the Editor of Palynology.Collection and analysis of the middens from Organ Pipe Cactus National Monument was supported by grants from the Southwestern Parks and Monuments Association to Owen Davis and to Tom Van Devender.

N2 - Packrat (Neotoma spp.) middens contain abundant and well‐preserved pollen. Pollen analysis complements macrofossil analysis of these biogenic deposits because it reflects both local and regional vegetation patterns. However, variability among and within middens is high, and the accuracy with which midden pollen reflects vegetation is lessened by this variability. The variability results both from midden inhomogeneity and from differences in the relative importance of the four major sources of pollen in middens: the air, plant material collected by the packrat, packrat feces, and the pelt of the packrat. The variability due to midden inhomogeneity is reduced by analyzing aliquots from large (ca 500 g) middens rather than the small (ca 10 g) subsamples used by previous researchers. The comparison of fossil sequences from Organ Pipe Cactus National Monument, Arizona, and Owl Canyon, Colorado, demonstrates the value of this procedure.
