South Fork Snoqualmie River

The South Fork Snoqualmie River runs for 30.8 miles (49.6 km) through a portion of the Cascade Mountains in western Washington, United States. Originating at Source Lake in the Alpine Lakes Wilderness of the Mount Baker–Snoqualmie National Forest, it flows through the mountains to Snoqualmie Pass, before descending westward, passing through numerous waterfalls and rapids. It meets the other forks of the Snoqualmie River after running north through the town of North Bend. The upper course of the river is a hanging valley, overlying bedrock and glacial deposits. The river runs through a large igneous intrusion and a valley shaped by the advance of ice sheets during the Last Glacial Maximum, around 14,000 years ago.
The South Fork Snoqualmie hosts salmonids such as cutthroat trout and rainbow trout, although the river's waterfalls and the presence of Snoqualmie Falls further downstream prevents the use of the river by anadromous (migratory) fish. The region was traditionally inhabited by the Snoqualmie people to the west and the Yakama to the east. Euro-American settlement in the region began during the 1840s and 1850s. The town of North Bend, platted in 1889, hosted logging operations and became a rest stop for travel over Snoqualmie Pass. The town grew after the construction of the Milwaukee Railroad in 1909 and the Sunset Highway in 1915, both of which passed through the South Fork valley. Interstate 90 now runs along the South Fork as it crosses the pass.
