Description :
Initial interpretation of the sediments from the Burmester core indicated that 17 deep-lake cycles, separated by shallow-lake and soil-forming intervals, occurred in the Bonneville basin during Brunhes Chron (the last 780 000 yr). The re-examination of the core, with new sedimentological, geochronological, and paleontological data, indicate that only 4 deep-lake cycles occurred during this period, apparently correlative with marine oxygen-isotope stages 2, 6, 12, and 16. This interpretation suggests that large lakes formed in the Bonneville basin only during the most extensive of the Northern Hemisphere glaciations.
