Intro:

Wrapping up the Ahklun Mountain Project (AMP), our research group now focusses on a state-wide compilation of the distribution and size of LGM alpine glaciers. This is a multidisciplinary effort that uses detailed glacial mapping and cosmogenic isotope chronologies combined with geographic information systems (GIS). Group members include Darrell Kaufman (NAU) and his students, William Manley (GIS lab CU INSTAAR), and Al Werner (MHC).

Research facets:

 

1999 to 2000

Major late-glacial readvance in the Ahklun Mountains and cosmogenic exposure dating.

[GEOLOGY article pdf]

2000 to present
State-wide compilation of the distribution and size of LGM alpine glaciers. Cosmogenic chronologies exist for the Ahklun Mountains (see below), the western Alaska Range, the Yukon Tanana Upland, the Kokrines Hills, the Chuilnuk Mountains, and the NE Brooks Range.

1999
Coring Lakes has been a major effort in the Ahklun Mountains. Many lakes have been cored, including those beyond late Wisconsin glacier limits to understand LGM environmental change, and those fronting modern-day glaciers to understand Holocene environmental change.

1996-1998
Surface exposure dating using cosmogenic nuclides has been my main thrust in the Alaska research. We've obtained surface exposure chronologies in both the western and northern Ahklun Mountains

1996-1999
The Ahklun Mountain Project (AMP) Homepage. AMP involves studying the Quaternary glacial, sea-level, and paleoclimate history of the Ahklun Mountain region of southwestern Alaska.
