Interbay is a neighborhood in Seattle, Washington consisting of the valley between Queen Anne Hill on the east and Magnolia on the west, plus filled-in areas of Smith Cove and Salmon Bay. The neighborhood is bounded on the north by Salmon Bay, part of the Lake Washington Ship Canal, across which is Ballard; on the south by what remains of Smith Cove, an inlet of Elliott Bay; on the east by 15th Avenue W. and Elliott Avenue W.; and on the west by the BNSF Railway. The Ballard Bridge crosses the ship canal from Interbay to Ballard. Much of Interbay is taken up by BNSF Railway's Balmer Yard. Interbay is also home to Fishermen's Terminal on Salmon Bay and the Port of Seattle's Piers 86, 90, and 91 on Smith Cove. Its main thoroughfares are Elliott Avenue W. (northwest- and southeast-bound) and 15th Avenue W. (north- and southbound). History It appears that the valley between Magnolia and Queen Anne was carved out during the Vashon Stade of the Fraser glaciation (roughly 14,000–17,000 years ago), A thin layer of sand throughout the area may date from a tsunami following an earthquake along the Seattle Fault Zone about 1,000 years ago. Although Interbay fell within the traditional geographic range of the Duwamish, early ethnographers did not record contact-era or earlier Native American villages in the area. Nonetheless, University of Washington ethnologist T. T. Waterman lists several native place names at or near Smith Cove and Salmon Bay. The Denny Party saw Interbay's development potential when they explored the area in 1852, but chose to settle farther south. Their settlement became the core of Seattle. Meanwhile, most of Interbay came to be owned by Ohio-born physician and poet Henry A. Smith (1830–1915), after whom Smith's Cove is now named. Smith and his wife, mother, and sister began with a claim on Salmon Bay near the present-day Ballard, and steadily acquired more land, extending their holdings south through Interbay to Smith Cove. In particular, the Smiths bought when so many other were selling during the 1855–56 Indian War (see Battle of Seattle). Smith established a settlement known as Boulevard roughly halfway between Smith Cove and Salmon Bay, along a street he called Grand Boulevard (present-day West Dravus Street). He farmed, practiced medicine, and wrote. His most famous piece of writing, published in the 1880s, purported to be an English-language rendering of Chief Seattle's speech
