Indian Rock Park in Berkeley centers on a volcanic rhyolite outcrop formed roughly nine to eleven million years ago and linked to fault-related activity in the East Bay. Long before it became a city park, the Huichin band of the Ohlone used these rocks for food preparation, gathering, ceremony, and storytelling, and acorn-grinding pits still remain in the stone. Donated to Berkeley in 1917, the site gained carved stairways during the Depression and later became important in Berkeley climbing culture, where figures including Richard M. Leonard and David Brower trained. It remains a neighborhood park where geology, Indigenous history, and climbing heritage converge.
