The middle portion of the Middle Fork Snoqualmie is characterized by miles of huge boulder gardens that provide a sort of slalom at moderate flows but build to dangerous holes at very high flows (above 3,000 cfs.) Generally speaking, the boulders get bigger as you go downstream. The toughest section is at 5.5 miles where giant boulders called House Rocks sit right in the main channel. The best route is usually to the right, but be sure to scout first. Rafting trips sometimes combine this section with the one immediately below it (the Club Stretch.)
