How did pinnacles national park get its name?

Pinnacles National Park got its name from the prominent rock formations known as pinnacles that rise dramatically from the landscape. These formations are remnants of an ancient volcanic activity that occurred millions of years ago. The park was officially designated as a national park in 2013, but its unique geological features had been recognized since it was first established as a national monument in 1908.
