Giant Rock, Natural boulder formation in Mojave Desert, California, US.

Giant Rock is a freestanding quartz monzonite boulder near Landers, California, covering 5,800 square feet and estimated at 25,000 tons. A rectangular section cut from its lower right side forms a deep recess with pale interior walls; a separate slab in front bears the etched words "God is Love" and the name "George Van Tassel." The boulder stands on sand.

A prospector dug out a room beneath the boulder in the 1930s and lived there for several years. In the 1950s, thousands of visitors came to gatherings organized nearby.

The name simply describes the boulder's size. Reports of Native American ceremonies here trace back to a letter by George Van Tassel citing local Indians and a rancher, and other sources call them unsubstantiated internet claims. Since the 1950s, UFO believers have gathered at the rock, and New Agers describe it as a spiritual vortex; graffiti now covers part of its surface.

Access requires unpaved roads that need a vehicle with enough clearance. Water and sun protection are necessary, as there are no facilities in the area.

In 2000, the boulder split into two sections, revealing a bright interior layer that was previously hidden. This crack runs for several meters and remains clearly visible today.
