| Abstract: | The last major ice advance of the Pukaki Glacier and subsequent onset of retreat occurred at c. 18,000 cal yr BP, and c. 400 m of ice surface lowering occurred prior to 16,165 ± 887 cal yr BP. Sediments and landforms near the lake outlet indicate initial formation of the lake somewhere between c. 510 and 520 m above sea level (asl), with initial lacustrine deposition of ice-proximal well-bedded Fancy Sands and localised coarse angular gravel accumulations likely derived from melting icebergs. Rapid ice retreat formed a large lake, at least c. 30 km long, at c. 510 m asl, with lacustrine deposition near the outlet of silty clay (Pukaki Pug) which contains as much as 40% diatoms. An age of 13,492 ± 293 cal yr BP for a piece of wood from Pukaki Pug is a minimum for withdrawal of the Pukaki Glacier from the outlet area. [ABSTRACT FROM AUTHOR] |
