Standing at 4,167 feet, Mt Si lies on the western margin of the Cascade Range just above the coastal
plains around Puget Sound, and towers over the nearby town of North Bend.
Mt Si and neighboring mountain, Little Si, were named after local homesteader Josiah "Uncle Si" Merritt,
built a cabin at the base of the peak in 1862.
The mountain was made famous in the show Twin Peaks, which was filmed in North Bend.
Only about a 45-minute drive from Seattle, the mountain is a favorite outdoor destination for residents
of Puget Sound. Between 80,000 and 100,000 hikers visit the mountain annually.
