Robin and I visited Kristi Wallace of the USGS lab that we met yesterday. She gave us a tour of her facility and explained all aspects of her research. Kristi does analysis on tephra, which is material ejected from volcanoes. I interviewed her for half an hour and have several photos from that interview. Later, I will edit the interview and have it on the polartrec.com web site as a podcast for all of you to see.
