‘Join Sugarloaf docents to learn about the history of Sugarloaf Ridge State Park—from its volcanic beginnings 3-5 million years ago, through the indigenous Wappo who tended its forests, fields and streams for over 10,000 years from their village of Wilikos at the headwaters of Sonoma Creek, to homestead settlements and their ingenious adaptations to our isolation and serpentine soils. We will also touch on the park’s natural history which intersects its human history in often interesting ways.”
