Ever wonder how the Black Rock Desert got its name? While most of the playa is conspicuously, and ironically rockless, there are remote areas where things are very different. Geologic forces - some volcanic, others still being studied by geologists - have left tiny vestiges of the area's namesake scattered about. Now you can own your very own collection of these intriguing artifacts without even having to bend over to pick them up. Available in three sizes. Each black rock is uniquely shaped and guaranteed to mystify participants and spectators alike. Mix and match sizes to create your own dazzling collection or let us do it for you with our Black Rock Assortment pack.
