Come visit a grand old show, a spectacular, nature- directed performance. The stage, walled by thick bamboo and plumed pampas grass, appears as an innocent pool of shallow water until time for the major attraction. Uprising steam and bubbling hot water announce the geyser. Then, while Mount Saint Helena and the craggy Palisades mountains stand silent as backdrops, Old Faithful Geyser of California throws a tower of thousands of gallons of water skyward.
