Constraining Ice Advance And Linkages To Paleoclimate Of Two Glacial Systems In The Olympic Mountains, Washington And The Southern Alps, New Zealand, Cianna E. Wyshnytzky

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis investigates glacial sediments in the South Fork Hoh River Valley, Washington and the Lake Hawea Valley, New Zealand that were deposited during the last glacial period. Research objectives were to reconstruct the style and timing of glacier advance and retreat in both areas and to assess the viability of luminescence dating of sediments in glacial environments.

Glaciers are influenced primarily by temperature and precipitation. Valley glaciers, like those in the Olympics Mountains and Southern Alps, are thought to respond relatively rapidly to climate fluctuations in comparison to continental ice sheets. Understanding how these glacial systems responded to past …
