"Sahalie Falls is the first and tallest of three major waterfalls along the McKenzie River. This sheer plunge of 73 feet is broken into two segments when the river is running at its highest volume but is more commonly a single powerful plunge. Sahalie is by far the most famous of the large waterfalls along the McKenzie, as illustrated in the falls being used in the Disney movie "Homeward Bound"."

"Well known as the falls may be, documentation of the falls over the years has seemingly had trouble establishing a firm height for the drop. Many accounts suggest the falls drop around 140 feet. A handful of gutsy whitewater kayakers who plunged over the falls measured the drop at 68 feet, while our measurement of the falls in 2010 came out to 73 feet. Whether the difference between these two numbers depends on the volume of water present in the river is unclear, but it is certain the falls are nowhere near 140 feet tall."
