Tower Falls
Near the Northeast Entrance Road —
US-212, Tower Creek tumbles into the Yellowstone river from a hanging valley. Like many of Yellowstone's waterfalls, Tower Falls began as a low ledge at the junction of two different bedrocks. Rock at the brink and underlying the fall is a tough volcanic breccia; the weaker downstream rock erodes faster. Where Tower Creek drops into space, imagine the missing streambed—a channel of softer rock long since worn away.
Just downstream from the base of the Fall, the Yellowstone River enters a narrow, swift-running gorge. tower Creek cannot downcut fast enough to keep pase—and is left hanging high above the river.
