Berkeley HistoryOutcroppings of weathered rock are a prominent feature of the Berkeley Hills, providing evidence of this area's complex geological past. Composed of Northbrae rhyolite, Indian Rock is an ancient volcanic remnant. Native Ohlone communities gathered at these outcroppings. Here they ground acorns into meal with stone pestles, eventually wearing bowl-like depressions in the rock.
