just off highway 14 less than 45 mins from los angeles are vasquez rocks. you may recognise this formation from the movies, they have starred in everything from star trek to blazing saddles to the flintstones. the striking shapes were created by rapid erosion during uplift some 25 million years ago & later revealed by further uplift on the san andreas fault.
what’s uplift? known to geologists as orogeny, this is the primary way mountains are formed on earth. an orogeny occurs where two or more (lithospheric) plates converge when the plate’s motion compresses the margin between them. this pressure forces the earth’s crust to crumble & uplift into the formations you see here. these will eventually (millions of years from now) become mountains.
ongoing tectonic activity on the nearby san andreas fault and its offshoot, the elkhorn fault which runs through the vasquez rocks natural area park, continues to shape, uplift, & expose the buried sandstone.
the rocks were named for famous mexican california outlaw tiburcio vasquez who used them to evade law enforcement in 1874. tiburcio was & is a controversial figure, with some believing him a ruthless bandit & others seeing him as a revolutionary opposing the american expansion into present day california.
vasquez entered outlaw life in 1852 when he was witness to the killing of monterey constable william hardmount. though he denied any involvement in the death vasquez fled law enforcement, going on to become a star figure in the infamous decades long roach-belcher feud. after being caught horse rustling in 1856 he spent five years in san quentin before organizing a prison break. in 1866 he was imprisoned again, this time for three years after a burglary in petaluma.
after he was arrested for murder in may 1874 vasquez, who was a charming & handsome figure with many fans throughout the west, sold photographs with & of himself to support his legal defense. he was tried for a murder that occurred four years prior during a robbery in tres pinos (now called paicines) where $2,200 (more that $47,000 in today’s money) was stolen from a store & three were killed. vasquez maintained throughout his trial that though he was an outlaw, he was not the killer. despite his adoring public & a written confession from another member of the gang, he was convicted of the crime & executed by hanging on 19 march 1875 at just 39 years old.
there are numerous geologic formations throughout southern california named for vasquez, including these rocks & robbers roost in kern county. he is buried in the mission cemetery in santa clara where fans still leave him flowers.
because of his affluent background, good looks, education, & sense of style, vasquez is believed to be one of the inspirations for the bandit-hero character zorro.
