Institute ofArctic and Alpine Research, Box 450, Univers& ofcolondo, Boulder, 80309. USA A regional paleoenvironmental reconstruction is presented for a north-south transect of late glacial pollen and insect fossil sites from the Rncky Mountain region. Altitudinal treelines were d e p r e d by an average of 671 m and summer temperatures were an average of 5.4% lower. The interpretation of paleoenvimnmental conditions based on insect f w i l evidence tends to show stronger departures from modem parameters than that b a d on pdynology. While clear evidence for late glacial occupation of the region by Paleoindians is s c a m , montane conditions were not 80 Bevere as to preclude human occupation. at least on a eeasonal baais. Newly diseovered sites of early occupation would benefit greatly from interdisciplinary studies. 9, 23 1 -234.
