the way up. In 1888 (1889 is also mentioned in some references) when John Muir first visited the Bay, this wall was and retreated from the sea by . Now, it stands retreated to , as a remnant of the old wall of the glacier system and has 16 major tidewater glaciers (10, 12 and 15 are also mentioned in some references). In 1899, wealthy railroad magnate Edward Harriman arranged for a maritime expedition called the Harriman Alaska Expedition to Alaska comprising an elite community of scientists, artists, photographers, and naturalists to explore and document the Alaskan coast. The voyagers, spent two months traveling from Seattle, along the coast of Alaska, to Siberia, and back again. In many ways, the expedition was an intersection of 19th-century science and 20th-century science. The expedition claimed to have discovered some 600 species that were new to science, including 38 new fossil species. They charted the geographic distribution of many species. They discovered an unmapped fiord and named several glaciers. John Muir and his friend Harriman who were members of this expedition were instrumental in governmental lobbying on National Park legislation says. The Harriman expedition was instrumental in documenting the extent of the glacier's retreat in 1899. John Muir was seeking corroboration of the continental glaciation theories of Louis Agassiz, whose controversial Etudes sur les Glaciers was published in 1840. The year 1893 recorded the arrival of the first tourist ship at the entrance to the Bay, at Bartlett Cove, which over the years has become central to the tourist trade in the Glacier Bay. By 1916, the Grand Pacific Glacier was at the head of Tarr Inlet, about from Glacier Bay's mouth. This is the fastest documented glacial retreat ever. In 1925, Glacier Bay was declared a national monument. For centuries, the Glacier Bay has been the home land of the Huna Tlingit native tribes of Alaska. Their oral traditions indicate being displaced by the last advance of the glacier. They continue to be part of the Bay residents and it is woven into the "tapestry of their lives". Geography Glacier Bay is subsumed within the larger about National Park and Preserve. The preserve, which is a spectacular ensemble of marine and terrestrial life, is delimited by: The Tongass National Forest borders on the east and north east; by the international boundary with Tatshenshini-Alsek Wilderness Provincial Park in British Columbia, Canada on the
