Roofer in Oakley

Indigenous history

Archeologists have found prehistoric sites in the Oakley area. One substantial shell mound was discovered early in the 20th century near what is now the east edge of town. The Northwest Information Center of the California Historical Resources Information System monitors the archeological investigations undertaken in Oakley. Around three-dozen such projects have been completed in the past 25 years, yielding only four prehistoric sites in the city. However, the information center believes there is a high possibility that other prehistoric sites remain within the city. To enable further archaeological excavation the site referred to as Simon Mound was purchased by the Archaeological Conservancy after many of the ancient settlement places had already been destroyed by urban encroachment. Simone Mound has provided bones and fragments from burial sites starting around 1000 A.D. and is near a similar Conservancy preserve, the Hotchkiss Mound.

The first accounts of identifiable cultural community in the west delta are attributed to the Bay Miwoks, who occupied the region between 1100 and 1770 AD. The Bay Miwok people, usually called the Julpunes or Pulpunes by European explorers, were organized into “tribelets”-political units that included several fairly permanent villages and a set of seasonal campsites arrayed across a well-defined territory.
