The 26th of June show featured the first part of a conversation with Sue Karl of the USGS. She was in town to give a talk on the geology of Baranof Island as part of the Natural History Seminar series. She began her study of the geology of Baranof Island doing graduate work in the 1970s and is the lead author of a geologic map of Baranof Island published by the USGS last year. In this part of the conversation we spoke mostly about the geological history of Baranof Island, including some theories on how and where the rocks that make up the island may have formed and what processes brought the to their current position.
