Indian Rock Park: A Volcanic Vista in Berkeley

Indian Rock Park, nestled in Berkeley's Northbrae neighborhood, is a unique destination where natural history, recreation, and stunning views converge. The park's central feature is a large volcanic rock outcropping, a remnant of volcanic activity from millions of years ago. This rhyolite formation, estimated to be between nine and eleven million years old, offers panoramic views of the San Francisco Bay, Oakland, and the surrounding areas. The land was donated to the City of Berkeley in 1917 by Duncan McDuffie, a real estate developer and conservationist, with the vision of creating a park that harmonized with the natural landscape. During the Great Depression, steps were carved into the rock as part of a New Deal project, making the summit accessible to all. Indian Rock has a rich history as a training ground for rock climbers. Pioneers like Dick Leonard, known as the 'father of modern rock climbing,' and environmentalist David Brower honed their skills here before making their mark on Yosemite and other climbing destinations. The park continues to be a popular spot for bouldering and beginner rock climbing. Today, Indian Rock Park is a beloved community space for picnics, sunset viewing, and enjoying the outdoors. The park also includes smaller rock outcroppings, grassy fields, and a picnic area across Indian Rock Avenue, providing diverse spaces for relaxation and recreation. Visitors can explore the nearby Mortar Rock Park, where the Ohlone people ground acorns, leaving behind mortar pits in the rocks, which serve as a reminder of the area's rich indigenous history.
