Tip of the Iceberg by Mark Adams
Although his heart belonged to the Sierra, John Muir had a long-lasting love affair with Alaska. In 1899, he embarked on his sixth and final journey there as a member of the Harriman expedition. In this book, Adams retraces the steps of that voyage. He meets with scientists, speaks with the people living there, and encounters his fair share of bears. But with receding glaciers and towns falling into the ocean, the shifting Alaskan landscape Adams encounters is a much different place than it was in Muir’s time. - Jade
