"Diamond Cascade" Top 5 Page for this destination Yellowstone National Park Off The Beaten Path Tip by GuthrieColin

The second waterfall encountered along Cascade Creek is Diamond Cascade so named for its 4 distinct and separate sections which form a diamond shaped form. The falls are probably the most photogenic along the trail and that is saying something. The vantage point just off the trail here is nearly optimal for viewing the falls whereas many others along the trail are somewhat difficult to see.
Surprisingly this waterfall is very poorly documented. The most I can find is a few web pictures of it and a brief mention in a book. This is bewildering to me since I found this to be one of my favorites for sure on this trail even though it is only about 15 feet (5 meters) tall.
For more information about this and other Yellowstone waterfalls check out Paul Rubenstein's book Yellowstone Waterfalls and their Discovery page 84.
Directions:
From the Ashton-Flagg Road west of the Grassy Lake Reservoir there is a signed turnout for the Cascade Creek trailhead. From there either drive or walk to the trailhead down a very rough road and hike a short distance past Pothole Cascades to the falls.
