View of the Qori Kalis moraines. The Qori Kalis glacier is off the photo, to the right.

As part of my dissertation research, I am developing three projects at Quelccaya Ice Cap in the Peruvian Andes. I am interested in:

1)     Defining the late Holocene extents of the Qori Kalis glacier, the largest outlet of Quelccaya Ice Cap. To do this, I am using surficial mapping and 10Be dating of moraine boulders.

2)     Establishing the signature of late Holocene Quelccaya Ice Cap fluctuations using sediment cores from lakes that receive glacial melt water.

3)     Determining the history of Quelccaya Ice Cap fluctuations during the Holocene by combining information from lake core records and the geomorphic record.
