Joaquin Murrieta is said to have used Brushy Peak as a hideout in the mid-to-late 1800s. Today, his legacy and namesake are ever-present throughout Livermore and the Tri-Valley area.  Have you ever wondered about the man whose infamy is such a large part of Livermore’s heritage?  

In 1848 a large deposit of gold stretching around 120 miles in rich veins was found in what is now known as Sutters Mill in Colma, El Dorado County, California. Discovery of the cherished metal drew the attention of over 100,000 opportunists, many of them newcomers to California and the majority of whom were young immature and rowdy men.  

The mining camps where people communed weren't necessarily the most luxurious of accommodations. Popular amusements included gambling your months' wages, spending the night at the saloon and fist fighting! Amidst all the chaos, it also wasn't rare for the occasional duel to break out as the result of some unfriendly words being said to one another. Although many gold miners were law abiding men, these mining camps were hot spots for lawlessness.  Since the state was still in its formative years, there weren't many civil officers around to keep the peace. 

The Myths 

During this time narratives were spreading throughout California of a particular character named Joaquin Murrieta. Depending on who you asked, this man was either a prestigious hero or a ravenous murderer and thief. Facts about Murrieta are rare and sparse, and a lot of his stories originate from myths. 

According to some, Murietta's infamous legend began in the summer of 1849 when tensions were high between Mexicans and Americans with the war between the two ending only recently in 1848. The tipping point was when American gold miners spearheaded a movement to remove "foreigners" from mines along the Stanislaus, Mokelumne and Tuolumne rivers. This eventually led to an anti-vagrancy law being passed which taxed all foreign miners $20.00 per month for mining permits. During that time $20.00 was more money than an average miner could make in a month. In response many Mexican miners opposed the tax and some even formed rebel groups.  Murrieta despised the tax so much that he and his groups of bandits would spend the next few years robbing and killing gold miners all over California from Eureka to San Diego. 

The Outlaw 

Another tale from people directly associated with him tells the story of a young Murrieta leaving his small village with his childhood love, Rosa, in search of riches in California during the gold rush. Although the couple made it to California, they had very little success.  American miners constantly terrorized Joaquin and Rosa and forced them off their promising claims. One night a brutal confrontation with a group of miners left Murrieta badly beaten, his wife assaulted, and his half-brother dead. It was then that Murrieta's infamous story began of living his life for revenge, robbing gold miners and searching for the men responsible. 

One feature many Murrieta tales share is his demise. According to accounts, over the course of three years California was plagued with robberies and murders almost all being suspected of Murrieta's doing. It became apparent to the governors of California that something needed to be done. The governors offered a reward for the capture or death of Murietta. 

The End?  

In 1853 Henry Love and a group of California Rangers finally caught up with the bandits where a bloody battle ensued leaving many dead and Murrieta ultimately beheaded. The story goes that Murrieta's decapitated head was preserved in a jar and put on display. To this day the death of Murrieta is up for debate. Some say the head in the jar does not belong to the real Murietta. His death was further debated when accounts of a letter sent to the governors of California read "I still have my head – Joaquin Murrieta". To this day we can only speculate how Murrieta's legend truly started and ended. 

Livermore Legacy 

There are over 100 landmarks named after Joaquin Murrieta and his horse gangs, including one in our very own city of Livermore. Now a historic winery, Murrieta's Well used to be a favorite rest stop for Murrieta and his horses. An artesian well bubbling water from beneath the surface was an ideal water source for horses being moved through the Livermore Valley all the way south to Sonora where they would be sold. In fact, many rumors say that Livermore was an area Murrieta would visit frequently as he passed through on his way north to the Sacramento Valley. Seeking refuge, he and his gang would often use Brushy Peak and its wind caves as a hideout from the law.
