Union Falls ht. 250 feet is a waterfall on Mountain Ash Creek, a tributary of the Fall River in the Cascade Corner of Yellowstone National Park. It is the second highest waterfall in Yellowstone exceeded in height only by the lower Yellowstone Falls. The falls got its name from members of the Arnold Hague Geological Surveys sometime between 1884-86. Geologist J.P. Iddings claims the name derives from the fact that a tributary of Mountain Ash Creek joins at the very brink of the falls, thus Union Falls. Access to the falls is via the Mountain Ash Creek trail and the Grassy Lake Road.
