Bronson / Brush Canyon Quarry


Looking out toward the western portal. This tunnel forks three ways and creates three portals to the east.



























County: Los Angeles

Primary Mineral: Rock, Gravel

Years of Operation: 1903 to the late 1920's

Nearest City or Landmark: Hollywood, Griffith Park

Depth: Approx. 150 feet, two side forks add an additional 100 feet


The quarry looks like a huge scoop carved out of a mountain. The mine is below this knife edged ridge.



























Did you know that there’s a mine right in the middle of Hollywood?  To be more specific, it’s an old gravel quarry, located on an unmarked dirt road in a southwestern section of Griffith Park.  It’s called the Bronson Quarry, or Bronson Caves, but you might know it better as the hidden entry point to “The Bat Cave”, located deep below Wayne Manor, from the 1960’s Batman TV show. Dozens of 1950's science fiction movies and westerns were also filmed here, including the classic mine scene from The Invasion of the Body Snatchers.

History of Bronson Quarry

Bronson Quarry was founded in 1903 by the Union Rock Company. The original name was Brush Canyon Quarry. This quarry extracted rock to be crushed for the construction of city streets. In the late 1920’s the quarry closed, leaving the man-made caves behind. These tunnels later became known as the Bronson Caves, taking their name from the same nearby street that late actor Charles Bronson used as his stage name. Mr. Bronson’s real name was Charles Buchinsky. Many low budget B-movies as well as huge feature films and TV shows were filmed here, due to this quarry's close proximity to nearby movie studios and the rustic, remote look of the location. Most filming of the western portal was shot at an angle, to give the illusion of a deep tunnel, but in reality it's actually quite short. 



Looking east; the three eastern portals have all been used in numerous sci-fi movies and westerns.

Is it an alien landing pad or did someone just get artistic? This rock circle can be found on the eastern side.



























Details

Bronson Quarry is located before the beginning of the fire road leading to the Hollywood sign. It is located in a hidden canyon off an unmarked dirt road near the end of the parking area at the northern end of Canyon Drive in Hollywood (inside Griffith Park). The road to the mine is on the right side. Parking is free, but is crowded on the weekends. The walk takes less than five minutes and is well worth seeing if you’re on your way to the Hollywood sign (a three mile walk). In fact, the quarry is visible from the sign and looks like a giant sinkhole in the middle of a mountain. There is a rough, steep trail that circles the rim of the mountain outside the mine, however there is one fairly dangerous drop on the southeastern side, so use extreme caution if you attempt this climb. Surprisingly you will find relatively few people in this area, even on weekends. Park rangers patrol the area regularly, so graffiti is "almost" non existent.

History of Griffith Park

When you think of Hollywood you usually don’t think of open spaces, but Griffith Park is actually one of the largest urban parks in North America, covering 4,310 acres. It’s four times the size of San Francisco’s Golden State Park. and nearly five times the size of New York’s Central Park. In fact, it’s so vast that mountain lions have been known to regularly roam the area. In 1882, Griffith J. Griffith, a Welch-born newspaper journalist and mining investor purchased the land that at that time was called Rancho Los Feliz or “Happy Ranch”. The Rancho was named after José Vicente Feliz, a Spanish soldier who was granted the land by the Spanish government around 1800, when California was still known as Alta California. At first, Griffith used the land to grow crops and raise sheep and cattle. Later, he started an ostrich farm in 1885 as a tourist attraction, selling feathers for three to five dollars each and had grand plans to expand the land into Los Angeles’ premier attraction. but just four years later, the ostrich park closed.

Griffith’s original investment of between $8,000 and $50,000 realized a million dollar profit when he subdivided the land, and sold off part of the area now known as Silver Lake in Los Angeles’ first real estate boom. In 1896, Griffith (who grew up poor in Wales) donated 3,015 acres of Rancho Los Feliz to the City of Los Angeles, insisting that the land should become a place of recreation for the rank and file masses, and not be made into a resort for the rich. However, Griffith’s plans for the park, which included an outdoor amphitheater and astronomical observatory were put on hold when in 1903 he shot his wife while in an alcohol induced rage and spent two years in San Quentin prison for attempted murder. Griffith offered the city $700,000 to fund his proposed improvements to the park, but with his reputation tarnished they would not accept the money until after his death in 1919. The Greek Theater finally opened in 1929, and the Griffith Observatory in 1935. The Los Angeles Zoo moved to it’s current location in 1966. The original zoo which opened in 1912 and sat on the site of Griffith's ostrich farm was abandoned, and is now known as the Old Zoo. Traveltown was added in 1952, and the Autry Museum of the American West opened in 1989.
