Story of the Byway

Long before early explorers came to the Northwest, Native Americans on both sides of the mountains carved foot trails across the Central Cascades, including Snoqualmie Pass, to hunt deer, elk and other game animals, fish for salmon, and gather berries. They also traveled to this area to gather wild plants for food, medicinal purposes, and basket weaving. Pacific Northwest tribes like the Snoqualmie Indian Tribe and Yakama Nation, used foot and horse trails across the Central Cascade mountains for trading as it had the lowest pass elevation in the territory.
