The Corona Heights neighborhood stretches between Buena Vista Park and Eureka Valley. The streets within Corona Heights were literally cut out of the large hill that once encompassed all of Buena Vista Park and extended all the way down to Market Street.
In 1899, excavation began on the hill to make way for the Gray Brothers Quarry and brick factory. The quarry had removed tons of rock and produced tens of thousands of bricks, creating a blasted landscape (seen in the photo).
George and Harry Gray (the Gray brothers) owned a total of three quarries in San Francisco. Besides The Corona Heights Quarry, One was located on Telegraph Hill, and the third at Thirtieth and Castro (now called Billy Goat Hill) located above Noe Valley.
They had a bad reputation that was well deserved. Of the bricks that were produced at the factory, many of them were used in the Cable Car beds. Subsequently it was determined that these bricks were substandard and had to be replaced. The community became enraged with the Gray brothers when adults and children were injured by falling rocks and homes were damaged by flying debris. Although the Gray brothers faced lawsuit after lawsuit, they kept quarrying.
In 1909, Carolyn Bush, their cashier and George Gray's secretary, was shot and killed by an unpaid worker who lost his temper. A few years later in 1915 George, by then a millionaire, was at the Thirtieth and Castro quarry. He was confronted by Joseph Lococo, a 26-year-old former worker whom Gray refused to pay back wages (of only $17.50). George was murdered by Lococo at the quarry. The quarrying and the company ended at that time.
After the Quarry 
Because of the quarry, streets had been cut out of the rock for transport vehicle access and from the general quarrying done to the area. This made the location prime real estate for people who began to build their homes on the streets cut into the hill.
Many of the neighborhood homes have views (due to the elevation on the hill), close proximity to underground transportation (MUNI), and are situated just a few blocks from The Castro, local restaurants, and neighborhood hangouts. At the top of the hill, where the quarry used to stand, there is now the Corona Heights Park: a large, open space with panoramic views of the city and the bay. Corona Heights Park also features a fenced-in, maintained dog park.
