This Nisenan Maidu site was protected by being part of a family landholding, and it was transferred to City of Roseville ownership. The City has included the spot as part of a regional park with senior center, etc. nearby, and has built a new museum and culture center on the site Nisenan Maidu people lived their everyday lives - a small village was here, and a number of petroglyphs illustrate a bit of their beliefs and practices.
The museum offers artifacts and a lot of information on who the Nisenan Maidu people were and are - and the local Nisenan people use this as a center for some of their celebrations and communal activities to this day, highlighting its importance.
Volunteer docents bring this place to life - guided walks reveal oak varieties, a large grinding area and how the Nisenan Maidu prepared acorn flour and products, a yellow ochre "mine" for trading for obsidian and other necessary products, plant materials used in food, medicine, basket and home products preparation, and often one can participate in grinding acorns, etc.
The center is particularly targeted to school groups, so check the schedule - and look for special events, nighttime campfires with stories and presentations, etc. to learn about the poorly understood and overlooked native peoples of this area and how they interacted with the earth in a mutually beneficial way.
