I have been studying geologic records of climate and environmental change in Alaska and elsewhere in the western US for the past 30 years. During this time, my interests have evolved from longer-term records of Pleistocene climate change — those preserved in deposits left by fluctuating Pleistocene sea level and glacial ice — to higher-resolution proxy records of climate — those preserved in lake deposits, particularly glacier-fed lakes
In Alaska, my students, colleagues, and I have completed projects involving:
- - Tephra stratigraphy
- Alaskan glacial geology - - Ahklun Mountains Quaternary stratigraphy
- Ahklun Mountains glacial geology
- Ahklun Mountains lake coring
And we have studied the outsantding geologic record of:
