National Geographic photographer David Guttenfelder is no stranger to dangerous situations. After graduating from college, he left his life in rural Iowa to cover the 1994 Rwandan genocide, an experience that kicked off a decades-long career of reporting on war, conflict, and major news events all around the world. But when the COVID-19 pandemic shut down travel to most countries, he took an assignment close to his roots—paddling the treacherously unpredictable waters between the Apostle Islands in Lake Superior. He describes what it was like visiting historic lighthouses and sea caves, and shares some surprising lessons he took away from that experience.
