Manifesting Giant Rock

Between 65 to 136 million years old, the "Great Stone", a seven story quartz monzonite rock, is said to be the world's largest free-standing boulder. Manifesting Giant Rock, a work in progress, reveals the local history, biographical information on key characters who lived nearby, events at the site, related publications and contemporary audio stories.

Working with the collections of the Morongo Basin Historical Society and the Twentynine Palms Historical Society and Museum;xNLx;the interactive timeline builds on research into Giant Rock begun in 2001, shortly after the mass split apart. Since this time, more information and photographs have become available online. This ongoing project will provide links in the timeline entries and juxtapose these histories with site images, interviews and investigations.
