The Costanoan, also known as the Ohlone, are a group of Native American tribes that originally inhabited the central coast of California. Their territory extended from the San Francisco Bay area to the Monterey Peninsula. The Costanoan people were known for their rich cultural traditions, including basket weaving and intricate storytelling. Historically, the Costanoan tribes lived in small, semi-nomadic communities, relying on local resources for food, such as fish, acorns, and game. They spoke several dialects of the Ohlone language, which is part of the larger Utian language family. Today, efforts are being made to preserve their cultural heritage and language.
