Trione-Annadel

https://www.parks.ca.gov/?page_id=480 https://en.wikipedia.org/wiki/Trione-Annadel_State_Park Trione-Annadel State Park is situated at the northern edge of Sonoma Valley and is adjacent to Spring Lake Regional Park in Santa Rosa. The rock formations of Trione-Annadel have played central role in its history: its volcanic origins, the Native American use of obsidian, the early 1900s mining of cobblestones, and modern hikers' appreciation of its volcanic rock outcrops. These lands were occupied by the Wappo and Pomo people in prehistoric times, who would have primarily inhabited the riparian zones and the marsh perimeter. Annadel includes some of the best example of undisturbed northern oak woodlands in existence. Visitors can enjoy the park's diverse wildlife and scenery during any time of the year but are perhaps most rewarded from April through June when most wildflowers are in bloom.
