The lower falls descend from the 590000 year old Canyon Rhyolite lava flow.Buffalo were everywhere.  Big ones, little ones, baby ones.  Traffic would stop for miles for people to look at them.  Mammoth Hot Springs.  There are walkways and bridges to walk on.Several key ingredients combine to make the Mammoth Hot Springs Terraces: heat, water, limestone, and a rock fracture system through which hot water can reach the earth's surface.

Today's geothermal activity is a link to past volcanism. A partially molten magma chamber, remnant of a cataclysmic volcanic explosion 600,000 years ago in central Yellowstone, supplies one of the ingredients, heat.Hot water is the creative force of the terraces. Without it, terrace growth ceases and color vanishes.Another necessary ingredient for terrace growth is the mineral calcium carbonate. Thick layers of sedimentary limestone, deposited millions of years ago by vast seas, lie beneath the Mammoth area.Another view of the walkway and stairs.  In that altitude I was out of breath.  I got lost going down the stairs, and Wes finally found me....hee hee.
