The linkages of the Upper Fremont Glacier isotopic record to the established paleoclimate record in the Quelccaya ice core appear to support further the first and only documented occurrence of a paleoclimate ice-core record from a temperate glacier in south-central North America. Further study of the archived ice core from Upper Fremont Glacier, in combination with lake-sediment records adjacent to the site, may provide a unique record of ecosystem response(s) to a rapid climate shift in a high-altitude, mid-continent ecosystem.
