That’s fitting, in some ways, because the rocks have served as one of the Star Trek franchise’s favorite backdrops ever since the show’s inaugural season, when Captain James T. Kirk scrambled up the jagged terrain during an

—cone-shaped deposits that develop as fast-moving streams empty onto relatively flat plains. The sediment likely hadn’t traveled far, much of it eroding from nearby uplands. Over time, the alluvial fan deposits were buried and cemented into thick layers of sandstone and conglomerate rock.

Over millions of years, the region was then reshaped by the interaction of

where the North American plate moves southeast and the Pacific plate northwest, contributing to the powerful tectonic forces that ripple throughout the region.

Eventually this tectonic activity led to the uplift and deformation of the Soledad Basin, with sedimentary layers gradually tilting, folding, and rotating. Once they were exposed at the surface, millions more years of weathering and erosion sculpted the formations further, removing softer material and leaving the more resistant sandstone and conglomerate fins and ridges that wow visitors today.

The rock formations represent far-flung moons and planets in
