Carved from a solid billet, the Multnomah was designed to represent a popular tourist spot near Portland. Multnomah Falls (photo credit, Wikipedia) is the tallest waterfall in Oregon and the second tallest year-round waterfall in the U.S. There are two drops to the falls, and this top is designed with a bump in the stem to resemble the middle pool.
This top is designed to spin from both ends with bearings top and bottom. The Multnomah has 12 milled grooves along the side and grip to display a spinning illusion of water movement; this is visible best in direct sunlight or on video.
