"The desert floor is not really 'sand' but a fine powder that swirls into great white clouds when the shifting winds stream into the valley from various directions -- obscuring all vision and directional orientation. When the rains come, the powders transform into slippery, sticky mud that bogs down any attempt to walk or ride on it. This is not the place one would expect to find a small temporary city bursting with extreme artworks. Yet Black Rock City does materialize each year in the weeks before, during, and after the Labor Day weekendand the celebrants appear to revel in the discomforts."
