Corona Heights is a neighborhood in San Francisco, California, just north of Market Street and Eureka Valley.

The community became enraged with the Gray brothers when adults and children were injured by falling rocks and homes were damaged by flying debris.

In 1909, Carolyn Bush, their cashier and George Gray's secretary, was shot and killed by an unpaid worker who lost his temper.

This made the location prime real estate for people who began to build their homes on the streets cut into the hill.

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.
