Late Quaternary-age arthropods were recovered from dry cave deposits and packrat middens located in the Glen Canyon National Recreation Area and several adjacent areas. Radiocarbon dates on the various deposits containing arthropods range from 1510 to 30,660 yr. B.P. The fossil assemblages yielded 57 identified taxa of insects, arachnids, and millipedes. Preliminary conclusions suggest a cooler, moister climatic regime during the late Wisconsin glacial time, and a mosaic of vegetation types, such as grassland and shrubby communities, unlike the present vegetation at the localities.
