Today really highlighted the geology of Southeast Alaska. Starting in Halleck Harbor, the huge limestone cliffs preserved fossils millions of years old. Heading up Chatham Strait on this clear day showed off the mountainous Baranof Island. Red Bluff Bay highlighted red-weathering peridotite rock, which was something I learned today about this area.
