Roush Creek Falls is a steep cascade in Washington’s North Cascades National Park, formed by Roush Creek as it flows south from Eldorado Glacier and quickly plunges over the cliff. At about 2,000 feet tall, it is one of the state’s tallest waterfalls. Its great height and dramatic position in the rugged, glacier-shaped North Cascades make it especially notable. The falls are directly shaped by seasonal meltwater from the glacier above, tying their flow and character to the alpine environment that creates the creek.
