The National Geographic Magazine, Vol. II., No. 3, July, 1890

Listen as a seasoned naval officer and geographer recounts his 1889 expedition aboard the USS Thetis, cruising the rugged coasts of Alaska and the icy waters of the Bering Sea. The narrative opens with striking statistics about Alaska's massive shoreline, setting the stage for a voyage that explores remote islands, towering glaciers, and the vibrant lives of native peoples. The tone blends scientific curiosity with the practical concerns of protecting American commercial and whaling interests in a largely uncharted arctic frontier.

The ship departs San Francisco in late spring, pauses in Puget Sound, and soon reaches the bustling port of Sitka before venturing toward the Aleutian chain. Early challenges include a storm‑tossed passage to Ounalaska and encounters with other vessels, such as the revenue‑steamer Richard Rush, engaged in seal protection duties. As the crew navigates icy straits and observes the stark beauty of the northern landscape, listeners gain vivid insights into 19th‑century maritime life, the strategic importance of the region, and the awe‑inspiring geography that still captivates explorers today.
