Text of sign:

 

Hanging Valley

 

Like many of Yellowstone's waterfalls, Tower Fall 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 pace - and is left hanging high above the river.

 

Falling water is hypnotic, like fire-gazing or wave-watching.  In 1874 Thomas Moran's sketch of Tower Fall helped excite national

interest in the new park.

In addition to the text there is a two dimensional  graphic explanation of the geology of the falls.  There is also an inset picture

of a 1874 Thomas Moran sketch of Tower Fall.
